More FSM confusion

The switching of identities during filming does leave a confused legacy. This includes the Spitfire FSM now living at Spitfire Corner disguised as PL279 ZF-Z. This is BAPC.268, built by TDL .for “Dark Blue World” and labelled as N3317 AI-A. It appeared at Spitfire Corner in 2005, apparently as MH978 and certainly coded OU-Z.Rebuilt in 2012 to its present form.
A second N3317, from the “Battle of Britain” film, is BAPC.71,coded BO-U; later P9390, it is now with the Norfolk & Suffolk Museum as P8140 ZP-K.
Some web sources have wrongly identified the Spit. sitting at Wellesbourne Montford for several years as BAPC.268. Photos clearly show it as N3310, another AI-A from “Battle of Britain”; this went to Abingdon in 2011 and is at (or on) the Lodge Hill Garage, still as N3310. It has been allocated BAPC.393
These are all IMHO; any argument will be more than welcome! So would photos of P9390
