Strafvollzug-Prison Police.
General, gabardine fabric, single piece cockade and yellow cap cord, gray piping, gray band, and yes the cloth backing seems to be the same colour/color backing as used on the Zoll/customs generals hat. I am told that this is the correct backing for the time this hat was made, and that a gray backing was used at a later period. Zoller's book shows it with the gray backing (page 80, abb. 40c) but does not provide the date of the hat shown. Two vent holes on each side of crown. Size 57 and dated "G" (1981). VEB 1856.
Officer,gabardine fabric, single piece cockade and silver cap cord, gray piping. Two vent holes on each side of crown. Size 57 and dated "A" (1977). VEB 1856.
Patrolman to senior Sergeant, high wool content with a two piece cockade and gray cap cord, gray piping. Two vent holes on each side of crown. Size 58 and dated "M" (1970). VEB 8049. My first DDR cap ;)
