There may be a comparison to be drawn between chicken's teeth and this item.
This component is part of the Observer's compartment hatch (entry/escape cover) mechanism of a de Havilland Sea Vixen.
This position was often referred to as the 'coal hole' because it was very cramped and dark and had very limited visibility. The idea being that there were fewer things to distract the observer from keeping his eyes on the radar screens.
Obviously designed with multiple purposes in mind (?), it also makes a perfect (and extremely rare) coat hook.
An unusual, yet very practical, memento of a classic British naval aircraft.
Part number and description engraved on the reverse. Supplied with certificate of authenticity.
