Apologies, my mistake on the ident- I should have remembered the bird was a swift (good to hear you're ex-72 Sqn, was that pre-Aldergrove?).
Do you have any thoughts on my puzzle re the role-shaped badges? Might 72 Sqn have been the only adopters of it?
The Cosford 'first Spit', as well as being the only aircraft I've seen with the mystery badge is also one of the few WW2-era RAF aircraft >without< a tailplane tricolour...because of the spear? (I admit I have seen some RAF Spitfires with large numbers on the tail instead of tricolours...)
