Very many thanks John for going to the trouble. It is most appreciated.
I have had the ‘.5’ for about 30 years. I got it from a UK collector who had had it some time.
It would suggest it is 8th AF as it is a heavy old thing and difficult to import in to UK in those troubled times.
I was rather hoping it was from a Spitfire ‘e’ wing. 🙂
