I have not been able to uncover much information about this gun, other than a few scale drawings and photos of a scale model put out by a Russian company. I’ve sometimes seen it referred to as a field gun rather than an ATG. From what I have found, the gun was either available in unknown “significant numbers” or was starting to become available in August of '44. Does anybody have more information on the gun, including how well it performed? And I’ve never seen photos of the gun in combat (staged or otherwise). Anybody have any they wish to share?
