Very unusual find, the 3 shell case pieces! It looks as if they were in the Process of being made into ashtrays but were suddenly abandoned before being totally finished! Was the maker a casualty,you wonder, and his project stuff just tossed out? The one in the middle was just starting to be flared out -in fact, it looks like he accidentally Split it in the one spot- and none of them have any notches for cigarettes yet. A fascinating find, for sure!
