Roger Freeman’s article in the August Air Pic quotes N5232V as being DF-V 122762, with a photo to prove it.

My photo shows DF-V but 122761 ( although serials were changed during filming ).

As he says N5229V was DF-T and remained at Manston it now seems possible that although DF-V was going to be scrapped at Bovingdon it actually flew to Biggin Hill for scrapping, possiblty as the MoD storage charges were higher at Bovingdon. So my photo appears to be N5232V.
