It has a silver case with these marks on it, below the clear marks there are 3 worn marks which look to be a single long stamp with diagonal corners. I haven't been able to make out any of the marks down there so I am hoping someone will know what the clear marks are - 2 stars there and a reversed crescent moon or 'c' in a circle. Many thanks in advance to anyone who can identify these. Of course the case isn't necessarily American. Pete
