RAF parachute quick release box
Parachute harness quick release box (QRB), type B2A. Typical early post war front disc. The box functions but one pin does not retract when the disc is depressed. This could be intentional as some had a harness plate permanently attached. The pin can be forced to retract but does not stay down. The base is partly sanded (removal of details?) and the screw heads are burred. Stock code S21823.
