Thanks Allen, sorry I did mean 127 Wing. I am afraid I am not much further on. I think it must be MA573, (also flown by George Beurling with 403 Squadron and lost in November 1943) because EN398 was his normal mount and was a Spitfire IXC. I have read that the IXe didn't arrive until 1944, although a clipped-wing Spitfire VIII was flown by Bett Houle in 1943 and so I assume MkIX versions were available. I wonder if the photograph is in error and that it's a photograph of 127 Wing in 1944?
