Hello,
X-Y EP305 flew in 229 Sqn winter/May 1943, and was then sent to Africa. Later X-Y __290 flew from June 1943, and EE741 in September. I did not fond mention of EP305 in 229's orb in July, so at Comiso X-Y EP305 could be flown by some high ranking officer (and thus marked E?). For example W/Cdr Pave from ME command visited Sicily on 21.7.43.
On operations at that time Spitfire JE JK533 was flown by W/Cdr Ellis, HD JL122 was flown by W/Cdr H. Dundas (and sometimes by W/Cdr G.K. Gilroy, who later got his 'own' GK-G JK143).
By the way EP305 had accident on Lentini, Sicily, 26.8.43 and was SOC 30.9.43.

Spitfire V trop SN-C of No. 243 Squadron RAF at Sicily passing Bf 109G Yellow 14 of JG 53.
It is possible that 243 Sqn used code A briefly, but only A-R EP650 is photographed at Maison Blanche.
B (242 Sqn) was discused before, and C (154 Sqn) is confirmed on Asibiz site.
D-K was personal code of D. Kains Spitfire EP312 in Egypt.
Also in Egypt Spitfire F-A ER934 flew in 73 Operational Training Unit and crashed 20.9.43, although some sources give code F for 72 Sqn and/or 72 OTU.

F was code of 81 Sqn in USSR

In Africa 81 Sqn's code was G, Nick was right.
Another Spitfire was coded G-G, EP566 of Greek 335 Sqn. Lost in Greece 2.10.46.
Air Vice Marshal Harry Broadhurst, AOC Desert Air Force, flew his personal Spitfire coded HB.
Letter I was often used as squadron code instead of number one on some Coastal Command's aircraft. Also famous Dakota AI of 267 Sqn was in fact A1.
J was 93 Sqn's code in Africa. It seems that ER675 was J-P and ER847 J-F, early 1943.
J-H was much later Mk IX MH944 flown by Col J.D.W. Human, 7 SAAF Wing at Forli, Italy, 1945.
L was 152 Sqn's code, but soon reverted to UM.
