Well i just got here , i have a small question , in this picture its a antitank artillery piece from a local cemetery , im curious what kind is it , at first sight it looked like a variant of a PaK but when i looked more at the barrel length and the muzzle brake and i trowed that idea out , i searched more and it looks more like a BS-3 russian antitank gun.
My question is what kind of gun is it?TUN.PNG

Yeah this is it!! I recognize that breach! And also that plate is higher because the gun is elevated , thanks a lot!
