Looks like 2 different models and wow do they look cool. Someone tell me these are not really Crossman in Russia and we don't have them. Looks like EDgun got a hold of a Crossman and made it cool.
I believe these are all custom made guns using Crosman as the building platform. I could be wrong but I do remember seeing similar possible the same guns years back and had similar thoughts as you. Those turned out to be Russian custom builds as well.
