LMG - Kg m/1940 (SAV). (Knorre-Bremse)

I want to give special honour to Stellan Bojerud who supported me with information.

 1940 there was a desperate need for machineguns in Sweden. The production rate of kg m/37 was rather slow and not suitable for modern production.

1940 a LMG was accepted called system SAV (Svenska Automat Vapen = Swedish Automatic Weapons).

The design was made by a German called Hans Lauf at Magdeburg Maschinenfabrik AG. However the patent starts out from the 22^nd of November 1933 in Sweden.
He had two fellow applicants from Sweden: Ivar Staeck and Torsten Lindfors.

Staeck and Lindfors got the patent for the double gas canal system and the double trigger construction.

This prototype was called LH33 and it later became Kg m/40.

A similar gun MG 35/36 (Knorr-Bremse)

1935 Hans Lauf became manager for the AG Knorr-Bremse, Berlin-Lichtenberg. There he got patent 19th of September 1935 for a similar weapon called LH35 which is modified to LH36 and this prototype was later accepted as the German MG 35/36. Wendelin Przykalla at Knorr-Bremse AG made some further improvements 1939. The weapon was most likely only designed at Knorr-Bremse but manufactured in Waffenfabrik Steyr.

This weapon was used by the Waffen SS in limited numbers as the MG 35/36

The mechanism works like the Swedish kg m/39 (BRNO LMG ZB26). When the bolt locks its rear end is pressed down to lock against the locking edge in the bottom of the receiver.

Kg m/40 was produced by Svenska Automatvapen AB (SAV), though all parts were manufactured by various contractors in the Stockholm area. SAV was only responsible for the assemblage of the guns.

m/40 fires only full auto. It is possible to shoot single shoots likewise with the submachine gun m/45 by very fast releasing your finger from the trigger.

The handle and the bipod are fixed to the gas-cylinder!

Test model based on LH 33 with double trigger similar to MG34 and grip safety.
	The m/40 used the same, 20-round magazines as the Kg m/21 and the kg m/37 (BAR), inserted from the left hand side. A similar gun was made in Germany by the brake manufacturer Knorr-Bremse. The FG.42 made by Krieghoff was based on MG 35/36 used the same system with magazine inserted from the left, just in front of the shooters face. Picture from Carl Gustafs Stads Gun Factory Weapon Museum.

The m/40 magazine has a reinforcement across (see pictures) which is different from the m/37 magazine but they are interchangeable.

	Note that there is a special guide inside the m/21 magazine to guide the cartridges in a careful way to avoid malfunctions in the kg m/40. To the left Kg m/40 magazine To the right Kg m/21 & m/37 magazine

The m/40 soon became quite unpopular among the troops and it was quickly transfered to the Home Guard who didn't like it either and shortly after the war it was replaced by the twenty years older m/21.
