Hello, I hope that someone can help me with this identification.
I just inherited a 42 lb. 20 in. high light blue naval? shell from a neighbor. I was told it was a practice round. The tip is made of an aluminium cone roughly about 4 1/2 long, solid with no markings. Tapping the side of the shell gives a hollow ringing sound as though it is hollow inside, so I am pretty sure there is no explosive contained inside. There is a 2 1/2 inch copper rotating band around the shell about two inches from the bottom. there is a two inch screwed in base cover in the bottom of the shell. The markings on the bottom and rotating band are as follows:
MOD-O AMCOT 5IN.-H.C. MK - 52 LOT 715 0969F
I would appreciate any information anyone can give me about this shell and the markings on the bottom. I am interested in small caliber ammunition and am out of my league when it comes to identifying something this big.
