If it’s green Big Ned, it could well be Spitfire and and as described. It’s not a bit I recognise but there’s plenty I don’t know! Was it the ‘red background’ vendor?

The guy who sold it me was a member on another forum, I can’t honestly say if he is this ‘red background’ character or not i’m afraid. I live close to RAF Cosford and will try and get down there to compare the piece with a Mk1 Spit they have there on display in the museum. It’s worth a try I guess. Any ideas or thoughts regarding the ‘M’ or possibly ‘W’ stamp?

Thanks, Ned.
