Rectangular rubberized cotton 'pillow', approximately 37 x 25cm. Two integral air chambers can be filled via one 'valve' in the upper right corner. Once inflated it provides a small pillow or cushion for unknown purpose. Stamped to one side 'With the Compliments of G.Q. PARACHUTE CO. LTD. Portugal Road, Woking, Surry, England' and with the GQ Parachute Co. logo. Also stamped 'Tested' adjacent to the valve. Inflates well but the original 'bung/stopper is missing (easily mocked up with a small piece of wood or plastic). A complete mystery - neck cushion/seat cushion? Stock code M17280.
