I have attached photos of some of the 20mm Mauser rounds in the collection. Most are self-explanatory. The flat tipped cylindrical projectile on the far right of the first photo is a U.S. loading of a German case done at Aberdeen Proving Ground during WWII. They were evaluating the gun system and loaded these as proof testing rounds. The case headstamp is eey 42 231.
The second round from the left of the first photo is a mystery to me. It is basically identical to the round to its left except someone has neatly cut off the front 1/2 inch of the projectile. The cut surface is not painted and there is no filling in the projectile cavity. I don't think it was done for any official purpose, but I can't figure out why someone would do that to a perfectly good round. Both are South African Practice rounds. Anyone have any ideas? Bob
