Можно ли купить 37-мм автомати́ческую зени́тную пу́шку образца́ 1939 го́да (61-К) в России в 2018?
37mm gun or 3.7 cm gun can refer to several weapons or weapons systems. The "37mm" refers to the inside diameter of the barrel of the gun, and therefore the diameter of the projectile it fires. However, the overall size and power of the gun itself can vary greatly between different weapons, in spite of them all being called "37mm" guns.
