40 mm Bofors AA guns made in GB and US

[Stellan Bojerud (RIP)]

I beleive only one Army 25 mm AA gun m/33 was made. There were however several Navy 25 mm AA guns m/32 produced.

The Soviet Union bought at least one 25 mm m/32 and license rights. The engineers L.A. Lokev and M.N. Loginov of No 8 Artillery Factory near Moscow made an upscaled version in 37 mm known as M 1939.

These were also produced in large quantities by factories 4 Krasnojarsk, 8 Moscow and 586 Kolumna.
