Here is a pic of what I have, anyone else have dummy rounds, or "neat" stuff to share?
The two 20mm, one is a WW2, like from a Hispano, date stamped 1943, the other is a modern 20mm case and dummy round. The two .45s, the brass jacketed round is stamped 1918, with an interesting 3 point "punched" crimp. The other is a 1943 stamped steel cased round. Normal 50 bmg, and a SLAP round from a 50 BMG. The 30-06 dummy is dated 1943, the 37mm round at the bottom, like the M3 Stuart tanks fired, is dated 1942. Dummy 40mm grenade and cannonball from a "Falconet" or similar cannon from who knows when.
