Of course Feggans Brown had already built the FSMs for the TV series “A Piece of Cake”. I’m aware of the following:

———- Spitfire cockpit, prepared for the TV but not used, now with Alan Partington in Catford

.

That cockpit is odd. It was built bottomless with the canopy sealed with aquarium sealant anf plumbing fittings on the bulkheads at each end. The original idea was to invert, slowly fill it with water, and film the occupant of one the aircraft that failed to fly under a river bridge drowing. The filming never took place. The cockoit was also about three inches too wide, not a problem until you try to fit correct sized mock up frames and instrument panel. It went on loan to an ATC squadron as a project but, as is so often the case, a change in OC meant that no work was carried out.
