Old military pith helmet. Cool safari type. The real thing and not a recent plastic reproduction.
Vietnam era? Purchased at an estate sale. The inside is marked 22 along with some other marks as seen in pictures. Adult size.
Looks like it might be missing its inside band. The top is meant to be pushed down? PLEASE USE YOUR BEST JUDGEMENT. No major stains or damage.
