RAF Parcahute hooks similar to those found on the Observer harness. These are a bit smaller (11cm top to bottom) and are cadmium plated steel rather than stainless. Probably used for other parachute harness straps (supply dropping etc) but could potentially be used for mocking up an Observer harness. All show use/wear and have light corrosion. Minor design variation between pairs. Three sets available - all sold in pairs. Stock code M5787/9/90.
