HobbyBoss 1/35th scale Gaz-AAA w/ Quad Maxim AA Gun

In 1928, Fedor Tokarev developed a quad mount for the 7.62×54mmR PM M1910 machine gun for use as a light anti-aircraft weapon, which was adopted in 1938 as the 7.62mm M.1931 4M ZPU. The 4M ZPU was mounted on a GAZ-AAA truck to create a mobile AA weapon. While effective against low-flying targets due to the high rate of fire, this setup was only used as a stop-gap measure until more dedicated anti-aircraft weapons could be developed and fielded.
