Tracking down fellow civil war cannon owners in the 90s talked a guy that had this in his garage with all the extras and offered at a price I couldn’t refuse Eva n though II was after civil war .
The gun was used as infinity suuport till the end
Wow! Always craved a 37mm M3 or M3A1 anti tank gun. Big enough, but not too big to be handled. My biggest is a DD 26.5mm grenade launcher. My son in law 3D prints the projectiles for me.
MP40’s are so smooth shooting. Sold mine to a friend and bought a Sterling L3A3 with the $. The Sterling rivals the MP in smoothness and controllability. The bolts on both never bottom out in recoil but just float back and forth.
