Talk:76 mm air defense gun M1938

What about the M1931?
Why is there no article on the Russian 76.2 mm M1931 AA gun? It was vastly more numerous than the M1938 and was used not only by the Soviets but also by the Germans and their allies, large numbers having been captured during the Wehmacht's drive into Russia.--Death Bredon (talk) 10:43, 27 May 2015 (UTC)
