The Boy's round is very good, you don't see many special loads in .55, mainly just AP ammo.
The .50 is fairly common, but the coloration of yours looks odd, perhaps just the lighting/pic. The year of production of that dummy is actually 1945, not 1940. As a savings move, Frankford just removed one of the 4s from 1944, and used those bunters into 1945.

the 50 bmg case is brass just tarnished badly

I also scored about 10 20mm empty cases most marked R.H 1943 O Z some marked DAC 20mm mk II 1943 no projectiles
