This cap, which exterior wise is that of an Enlisted hat, has absolutely fantastic piping which butts near invisible. The insignia is extraordinary, and the interior, which has a beautiful golden satin lining, has the SS runes under the sweat diamond, is size 57 1/2. Under the sweat band, it is marked HB 39 and the visor is RZM SS stamped. There is no RZM tag nor has there ever been. The lining is beautifully pleated and extremely tight. No blousing on this visor. Came originally to me years ago, and has just been recently repurchased. Only a guess, but I would guess it was worn by a senior NCO who had some money, and wished to purchase a superior visor.
