WW2 Period Royal Navy Captain's Cap.
A superb and typical WW2 example. The dark blue cloth cap retains original bullion cap badge. Interior with leather sweatband and lining, the latter with a Portsmouth tailors details. Very Good Condition, one of the best I have had. The diameter of the sweatband is about 22 inches. (Sold as a historical collectors item only).
This pattern of cap worn by Captains and Commanders.
