J. Theofron Munktell was the fourth child in Kärrbo Vicar house and his father was next to be priest in Sevalla and married to Christina Nohrborg. Theofron was born on the 20th of March 1805 and died at the age of 92, 1887. He got his education by his father in their home.

Early he showed mechanical talents. His first job was at an instrument works in Västerås. At 17 years of age he was approved as a pupil to engineer Gustaf Broling at coin works in Stockholm. Here he got the task to construct tools for coin production..

Through good result he was raised to supervisor. Through this he became notified and got a stipendium to travel to England for studying production method specially for steel casting. The result of this journey steel became better, but as the demand in Sweden was too weak this production was ceased. 1833 Munktell moved his works to Eskilstuna and built upp Eskilstuna Mechanical Works.

Here new types of machines saw daylight. Theofron was most interested to rationalize agriculture help machines. Now he could get information from Samuel Owen and Niclas Edelcrantz about steam engines.
Tractors and agriculure machines in many different variations were constructed. One product which gave Munktells a good economic start was locomotives with a start from 1847 to about 1970. But this type of constructions was not an interest of Theofron Munktell.

He instead swithced over to locomobiles. They were normally  placed two an two on each side of the field and with wires hauled multiplows. Later 1913 her instead constructed a tractor, with a crude oil engine which could haul a combination of 5 plows.

From the late 1850th several large steamers and can be seen at Technical museum Stockholm and a more modern variant at Munktell museum.

In order to succeed to construct so many different agriculture machines Theofron had many assistants who also made constructions of their own. Thearmenius was one who constructed threshing machines. They were  later produced in Arvika Sweden. Munktell Mechanical works were merged with Bolinder to Bolinder &Munktell, B/M or Munktell Mechanical Works 1879.

Theofron now retired from active involment in the lead. Instead his sisters son, Theofron Boberg, took over the technical lead.

Forstlingen story

Forstlingen 2008

Forstlingen II. Copy of the first engine bult in Sweden. Note that it is placed on Swedish standard rail.
The first Swedish built steamer has the connection with railway building between Norberg-Ängelsberg to be a support steamer while building the railway and after that to pull ore to Ängelsberg.

1847 started the building oft the steamer and was ready for delivery 1853. The railway was not ready until 1856. Already 1853 the building company went bakruptcy and the steamer was sent back to Munktells. Here it was redesigned to 1453 and them sold to Nora Ervalla railway 1855. Depending of the bridge catastrophe over Järle river a 3 year delay arose. In this way Norberg Ängelsberg became the first railway with steamer pulled wagons.

This steamer was first aimed to be a building loco. The order went to Munktell works. Here Fredrik Sundler orederd and harald Asplund constructed a loco with 891 rail width. The loco was first test driven 2 of June 1853. It took almost 3 months to transport it to Norberg.

This loco could pull 16 tons of cargo and had a self weight of 17 tons. During the building it was much used before it went back to Munktell after bankruptcy. It was resold to Nora Ervalla and rebuilt to swedish normal rail width 1435 mm.
This loco was used to 1869 when it was stated to be complete worn out. For a long time it was for sale and lastly sold 1871 to Halldins Works in Örebero for 800 Skr. After this it was scraped 1882.

Nevertheless the association could trace some parts when the reconstruction had started. One framside, cylinder and one wheel. The boiler was sold to Mosebcke Stockholm, to be used as a heater. Some of these parts are stored at the Swedish railway museum Gävle.

The new steamer "Forstlingen II" was ready 2004 and was first driven at the 150 years jubilee of Swedish railways. See my photo from Ekeby market with a happy passenger 2008.

Note. In Norberg Sundel had disappeared and new money showed up 1854. A new loco was ordered from Munktell. This became a so called Fryckstad type and was the third loco produced. Totally Munktell made 10 and they sold 31 locos. The second which was delivered went to Fryckstad and is spared at railway museum Gävle. See picture.

Steam wagon


An old fashion rail type which was bought from England. Ref. 1
Museum info about steam wagon. Ref. 1

Picture shows a part of crankshaft in the opening of the floor. Ref. 1


Transport wagon with inbuilt steamer for drive.

When all railways were building i Sweden it showed that it was a need for shorter local transports to the working places. Other types of personel transports were of small importance. This was the cause why this type of self moving wagon was built. It was to expensive to use a engine and wagon for this purpose for the small amount of passengers

This very wagon came from Växjö - Alvesta Railway. Totally there were 7 built and 2 had 3 wheel axles.

This wagon has serial number 5 (from 1887) or 2. Diferent information in Munktell history book.

Munktell was cooperating with OFWJ and built the machinery with boiler while OFWJ made the rolling wagon.

1899 Steamer Sven

Info of steamer build 1899, shown at museum. Red. 1


The real brag project in the museum is this renovated steamer from 1899, which gave 400 ps. It is driven for demonstration with pressurized air. An earlier and bigger one can be seen at Technical Museum Stockholm. Ref. 1

This steamer has a slight connection when Swedish lost of Finland to Russia. One of the Swedish rifle factories was at this time situated in Söderhamn and this was to close to the Russian border after the peace treaty in Kalix

One new factory was established 1813 in Eskilstuna. This was named Carl Gustafs rifle factory. To get power for this production a waterwheel was built in the Eskilstuna river.

During the second half of 1800, Eskilstuna Mechanical Works was established (1832), which the through mergings became Munktell Industries 1880.

This new company also took power from Eskiltuna river but more modern with turbines. However the rifle factory was own by state and when it was low level with water Munktell Works couldn't use their turbines.

For this reason it was decided to build 5 steamers in order to generate electricity 1899. 2 were installed at Munktell and were used to 1951 After this one was scrapped and the other sold to Näsviken factories outside Åmål. No info about the others.

In Åmål  it was used for 15 years till it was stopped and was taken over by the local home society. In this ownership it stood for another 35 years before the 25 ton heavy machine was demounted and transported to Eskiltuna 2001.

This steamer got the name Sven as he was the main enthusiast who controlled the mounting in the museum. It is today demonstrated moving by compressed air.

Historical notes about locomobiles.

Already 1853 Theofron Munktell started with production of locomobiles at his works in Eskilstuna. This production was further developed at Munktell Mechanical works and covered all different power types up to 400 ps.
These machines got the acknowledgement among all "the Grand Prix" at an international exhibition 1912.
The shown locomobile has production number 5375 and was renovated during 2009-2011 by veteran mechanics at Munktell museum. During wintertime it is deposited at the museum by Madesjö Hembygdsförening, Madesjö.

This locomobile was delivered to South Wisselfjädra Steam Thresh Society on the 21 st of November 1916. When this society was cancelled 1940 it was bought by the egineer who continued to use it up to 1957 on his on farm

After his dead it was placed outside exposed for weather and wind. There were many who wanted to buy it as scrap but the relatives had given their brother a promise not to scrap it and because of this it was left.

Locomobile and the tractor collector Ruben Blom found the machine in the beginning of 1970 and it was with the help of P.O. Karlsson Blåningsmåla mill, who had good knowledge about locomobiles in Blekinge county and in the southern part of Småland county. When the relatives understood that it was going to be preserved a sale was possible.

It is shown unrenovated and for the moment not drivable but as a whole in good stand. SK-2 was produced in 35 copies and this machine is today one of two preserved having production number 5668.

Owner today is Ruben Machine historical collection Götene.
Selfgoing locomobile SK-4
Text after museum info.

SK-4 was the middle size and the most sold type of 3. It was produced in 120 copies. The shown was delivered to C.J. Törnkvist, Rinkeby Smedby on the 22 nd of July 1915. It was after this bought by Östingstorp-Sjöbo Tresh Society. The engineer was the farmer Ragnar Andersson, Sjöbo, who when this society cancelled took over the ownership.

When he passed away 1972, his wish was that it should be donated to the local agriculture society which was Madesjö Society. 1972 a formel ownership was made through the estate by the respresentative George Petersson. A formel letter of gift was written 1991, when the society also got the belonging tresh parts, halm press and yhr transport wagon. The machine is stored at Kristvall Old Priset yard where it are shown during midsummer celebrations.

Since 2011 this locomobile is stored at Munktell museum in Eskilstuna during the winter. It has also been renovated. It is sent back to Kristvalla during the summer.

Here is only shown some of all tractors in the museum.


One Lanz tractor photoed at a small farm in sothern Germany, which I visited 2003. See text BM10. Ref. 1


Hot-Bulb engine


Fuel oil
Munktell type 30-40 1913. 2 cyl. 2 stroke hot-bulb engine given 30-40 ps. This tractor had the power to pull a 5 plow tool and made the same work as 16 horses and 8 man. The first tractor had a length of 5,8 m and a height of 3,3 m. This was a giant on Swedish fields. It was sold to Gimo Works in county of Uppland 1913 and was aid 1p6625 Skr new, an impressive sum of money at this time. It was sold to a farm in Skåne 1927. Bought back to Munktell 1954 and renovated. 31 copies were built. Ref. 1
  Picture shows the drive power wheel. It was dangerous to get a stop when working in the field. By oveload this little gear wheel could easily broke. I suppose that there were gears following as spares. Ref. 1
Worm drive for steering. Ref. 1
The smaller type 30 1917. This could take a 3 plow tool. Equipped with 1 cyl hot bulb 2 stroke engine giving 20-24 hp.
The glowing hot-bulb between the feet of the driver. Ref. 1
Munktells 20-24. 1930, 2 cyl 2 stroke 22-26 ps fuel oil. This is the first tractor which has found the modern tractor design. Engine, gearbox and rear end were built together. All active parts were produced by swedish nickel steel. Totally there were 1579 copies sold at a cost of 5225:-. It could take a 2 plow tool and was also used for tresh works.
Munktells BM2 1939, 2 cyl 2 stroke hot-bulb, 32 hk. This was an updated type 25 equipped with pedals instead of levers. Was converted during WWII with wood  gas aggregate. This was rather costly. Was able to pull a 2 plow tool. It was soon replaced by BM3. Built in 473 copies while BM 3 only was produced in 55 copies.
BM 20 1944, 2 cyl 2 stroke hot-bulb and 41 hk. It could take a 2 plow tool. Now the construction took in consideration when measuring how stiff the soil was. In this case the middle stiff soil is counted. The tractor had rubber wheels and a higher transport speed and also good brakes. This type was also used for work in forrest. Munktell had now cooperated with Volvo during the war and the type got the Volvo version of Hesselman engine, with the type name T43. 3400 copies for 13110:-.
T43 with Hesselman engine in Volvo color. 1946, 4 cyl 4 stroke fuel oil or kerosene 48 ps. Could take a 3 row plow and 6 feet tresh. Was an alternative to BM20 but as a whole just a BM20. This tractor was in use up to 1975 when Munktell museum bought it. 1600 copies produced for 12900:- each.
 Volvo T21, 1946. Volvo 4 cyl kerosene 22.5 ps, delivered just after the war and was the tractor for small farms. The main model T20 was produced in 1800 copies and production continued up to 1959 when 30000 copies were delivered. Now the slogan arose that "never know how old a Volvo will be". The one in picture is produced 1946.
BM10 was a concurrent to T21, but had a 2 cyl. 2 stroke hot bulb with 23 ps. It could take a 2 row plow which was connected hydraulically. It was a good tractor for row cultivated crops. The exhaust pipe was first directed backwards but was quickly changed to point uppwards and also equipped with a blow out unit. It was a German engineer who came to Eskilstuna during the war who constructed this tractor. BM10 had big connections with the pre war German tractor Lanz. 6400 were produced and sold  for 8690:-
BM230 Victor 1955. 2 cyl. diesel 33 hk. This model became very popular and could be used for everything on the farms. It became the start model for the forrest tractor BM230. It was produced in 15905 copies and sold for 13500.
This is the last of the Volvo type 1957 developed tractors. It got the nickname "Krabat", while the BM version was named "Terrier". The type was named T425 and was equipped with a Volvo B16 engine with 32 ps and had petrol in the tank. 11193 copies vere sold.
Advertizing for BM Victor. Time had come to put women behind the steering wheel.

Here is only shown some of all engines in the museum.
A Bolinder engine from 1953. It is a four stroke diesel giving 11 ps. The engine was used in smaller boats for timber handling and also for spare time boats. The name is type 1051 BR and was developed out of the tractor engine 1053. 105 means cylinder diameter and 1 means the cylinder number. 
WA30M21122 was primarly an engine for fishing boats. 2 cylinders 2 stroke hot bulb which gave 156 ps. It has a cylinder volume of 59 litres. Note the central lubrication by ASSA system. Was started with pressurized air. This engine was mounted in a trawler from Lysekil, which was sold to Norway 1965.
One Bolinders W7 S6, 6 cylinders 2 stroke hot bulb engine giving 180 ps. Normally connected to a genarator. In this case from ASEA. Were mostly sold to marine boats and mounted, side by side, in smaller mine sweepers. This very engine was mounted in the fortifications of Boden. In this position it should work as spare power if Harsprånget power station was destroyd.
 Bolinders W7 M15. A 2 stroke, one cylinder, fuel oil engine from 1920. It gave 25 ps and was most common during the 30 to 40th.This engine was first sold to Gotland but was then transferred to Karlstad in order to be mounted in a spare time boat. This was never done and after 7 years the museum bought it.
  There was an engineer at Munktell with the name Rundlöf. He developed this 2 cylinders fuel oil engine 1915 with hot bulb and 20 ps. It was sold during the 40th  and used as a stationary power station, but was also mounted into boats. The engine could be bought with 1, 2 or 4 cylinders. With this type it was easy to get the opposite rotation. 
 One, two cylinder engine equipped with backlash gear box. No closer informations
 In Nacka city there was a firm named J.A. Svensson which started with engines for kerosene. The firm is also known for the engine for the first submarine in Sweden to which they delivered a kerosene engines driving a generator. Hajen 1904. There were other smaller engines named Avance and sold for Kerosene drive, exported over the whole world, mainly to Russia. When J.A. Svensson ceased, Munktell took over the production. At this time 1910 the drive was normally fuel oil. There were engines with 4 cylinders and 360 ps.. Munktell ceased this production during 1930.
 This is a Columbia engine and it is used with fuel oil. Produced 1910 and gave 9 ps. It had something so simple as drip lubricadtion. The name came from that many were exported to just Columbia. One visitor told that he had seen one pumping water as late as during 2000.
A Columbia engine was normally mounted on a small 4 wheel wagon. The engine can be recognized for the small cylinder which mixed fuel oil and air. All were 2 stroke and gave 9 ps.
