[Alex Smart]

Hello,
What I have so far on JL212 Spitfire Vc.

http://www.spitfires.ukf.net/p053.htm

JL212Vc TCBAF M46 33MU 4-4-43 47MU 15-4-43 Liberian 5-5-43 Takoradi 29-5-43 Middle East 23-6-43 134S 451S u/c collapsed on landing Idku 2-8-43 SOC 1-12-43

Spitfire the history
JL212 - M46 - 33 MU 4-4-43, 47 MU 15-4(-43), Liber(Liberian) 5-5(-43), Tak(Takoradi) 29-5(-43), ME 23-6(-43), SOC 1-12(-43).

Fighters over the Aegean
Page 50, "they were our own Spits being flown by German pilots [two of these would have been JL212/V and W, former 74 Squadron aircraft]".

You will see that in the earlier publications there is no mention of JL212 being with 74 Squadron coded a/c "V".
So if it did serve with that squadron does anyone know dates of service please ?
Also any info on the other Spitfire coded "W" what was her serial number ?

Thank you
Alex
