The 7.5 cm kanon PL vz. 37 (Anti-aircraft Gun Model 37) was a Czech anti-aircraft gun used in the Second World War. Those weapons captured after the German occupation of Czechoslovakia in March 1939 were taken into Wehrmacht service as the 7.5 cm Flak M 37(t) or Flak Skoda. The Germans sold many of them to Italy where they were designated as the Cannone da 75/49 or 75/50. Surviving guns were taken back into German service after Italy's surrender in 1943. 20 were sold to the Finns in November 1940.[1] Twelve were in Luftwaffe service between April and September 1944.[2]


The gun had a semi-automatic, vertical sliding block breech that automatically ejected the cartridge case after firing, but had to be hand-loaded for the next shot. It had a standard hydro-pneumatic recoil system and a muzzle brake. It could fire a 6.5 kilograms (14 lb) armor-piercing shell for direct fire. It was intended for motor towing as it rode on a two-axle carriage with pneumatic wheels, but could be towed by horses if necessary. The side legs of the cruciform mount folded for transport.[1]
