Of course Feggans Brown had already built the FSMs for the TV series “A Piece of Cake”. I’m aware of the following:
BAPC.202 Spitfire MA467ended up at Maes Artro Leisure Park, by Llanbedr. On e-bay 2006 and not heard of since
BAPC.209 Spitfire MJ751 FJ-N now at the Niagara Falls Museum
BAPC.283 Spitfire, serial not known, now in store in the Isle of Man, previously seen at Jurby
———- Spitfire cockpit, prepared for the TV but not used, now with Alan Partington in Catford
From their build date of 1990, I suspect that Spitfire BAPC.206/MH486 and Hurricane BAPC.205/Z3427 at Hendon might also be Feggans Brown products, but am waiting confirmation or otherwise.
