Hello all, I'm quite intrigued by a 37mm sub-cal round I've come across. I'd greatly appreciate any information you can provide, particularly about the cartridge caliber for the barrel insert, its country of origin, And the gun it was used in. Also, there are no visible markings.
The projectile would be 37mm.
The case would be 73mm.
The overall length is 130mm.
Rim diameter 43.75mm.
Chamber diameter 12.4mm.
Muzzle diameter 10.8mm.
The body is made of brass, and the barrel is steel.
Thank you for your time.
