Frank,
Thanks for your speedy reply, precisely what I was after!
I have O-888675 1/Lt John Barton YERBY USAAF, 340th FS/348th FG, date of death 26 June, 1944.
Yerby had previously served in the RAF (116159 F/O). He served on No.54 Squadron RAF in the defence of Darwin (1943), and later transferred to the USAAC. It is mentioned in several places that he was an ex-member of an Eagle Squadron, I can't find any evidence for that.

Appreciate your help.
Would someone have a serial for Yerby's P-47 on 26 June, 1944?
Col.
