HI, I'm looking for information on a 20mm projectile I picked up in an abandoned house on a western South Dakota ranch. It appears to be cast in 2 pieces the nose and about half the body is a lighter gray color and slightly larger diameter (by about .02 inch) than the lower half which looks like plain steel. All of it is attracted by a magnet. In the base is a hole about a quarter inch in diameter and filled with something relatively soft. It was very rusty, as I would expect steel or iron to be after 50-60 years, I soaked it in muriatic acid to remove the rust. There are small remnants of black paint around the lower half. I managed to make out the numbers "LOT 09 4520MM M95" on the bronze/copper ring at the base. Would anyone here be able to tell me if this might be dangerous? I'd love to know the back story on this. Do the markings indicate a date? is there any way to know if it has been fired? Any information you could provide would be greatly appreciated! Thanks! |
