This 20mm Hispano was a nice gift from my fiancés grandfather on the weekend. A single drilled hole in the case to dump the powder otherwise untouched.
Headstamp is BBC 1941 20MM which is from Bridgeport Brass Co.
I havent been able to get a name for the projectile which I presume is AP of some sort. Not sure about the stamping on the projectile either.
Any suggestions.
Thanks
