GR3 XV752 is no longer at Bletchley Park. It was moved to the South Yorkshire Air Museum (Aeroventure) in December 2011. The airframe is still an MOD asset and is under the charge of 1053 (Armthorpe) - Air Cadets Squadron, but is on loan to the Museum. Having extensively researched the aircraft history when I was at 2366 (Bletchley Park) Sqn ATC, I can confirm that 752 saw extensive service with 1F Sqn.
A lot of work went into that and securing it's future, please look elsewhere. As said rescuing one of those I listed earlier with a relevant history from a terminal fate would be a good result.
