Steve, in the Internet Archive/Library of Scotland digitised Air Force List issues for April and July 45 there are just four men surname Booth, initials some variant of JF etc.
Three of them are F/Lts, leaving just
S/Ldr JFH Booth DFC 37958 (col 556)
Entered the RAF on a SSC in 1936:"Acting Pilot Officers on probation with effect from and with seniority of the dates stated:London Gazette https://www.thegazette.co.uk/London/...4321/page/5793
6th Aug. 1936. James Frederick Henry BOOTH."
March 1939 Air Force List (own copy):
JFH Booth Pilot Officer (wef 6 Apr 1937) No 70 Squadron Habbaniya.
March 1943: DFC"Squadron Leader James Frederick Henry BOOTH (37958) No 142 Squadron"London Gazette, no citation: https://www.thegazette.co.uk/London/...upplement/1309
So, S/Ldr James Frederick Henry Booth DFC 39857, ex 70 Sqn, ex 142 Sqn.
More entries in the Gazette for you to follow if wanted, some under full name, others under surname/service no.
