As posted on another forum. Again, any help would be appreciated.
“Gentlemen, I’m trying to get some info on the 105mm AP. It is marked on the top (sintered iron??) rotating band with the following: KVS-S-S-63-105MM-T182E1. Length of the round is 10.75”, weight is 33lbs, and has double rotating bands that appear to be, as said earlier, sintered iron. Thanks, Bruce."
Later info that I had come upon is that this round might have been associated with the T140 105mm Tank Gun Project of the early '50’s that was mounted on the U.S. T54, T54E1 and T54E2 tanks. Thanks, Bruce.
