Good Evening: I recently purchased a somewhat strange item I cannot identify, but I believe it to be a projectile from a German 75/50 anti tank round. This object is 6.75 inches long, 47.8 mm in diameter and, get this, weighs 8 pounds! It is one of the heaviest objects for its size that I have ever lifted. It has no markings whatsoever. It does draw a magnet. I recently saw a picture in Ian Hogg's book "The Illlustrated Encyclopedia of Ammunition" on page 238, middle picture, that shows a bullet shaped sub munition inside another shell. It looks exactly like that, but I wanted to be sure. Sorry I can't upload a pic right now, but will do so in the future if this mystery continues. Thanks ladies and gentlemen.
