Nearly 80 years old.  Mostly great condition.  I wear an 7  1/4...tried that hat on and it was really tight   Tagged Lg, but may be more of a 6 7/8 to 7. 

There are some obvious little pin dot marks in two areas on the cap   ...please see pics for descriptions.  Fairly rare piece.

If there's anything I can do to try to help with sizing please send a message.  Because it's leather  it's difficult to measure.  I'll do what I can
