Just to keep the record straight, the Spitfire 14 became operational with No.610 sqdn. on 8 January 1944Maybe...but the P-51H didn't fly until 3 Feb 45 whereas the Spit XIV entered squadron service in Dec 43. The Spit 21 was in squadron use in Jan 45 so even that's not a true counterpart of the P-51H. The Mk22 was probably the closest from a timescale perspective...so how about that comparison?
and the P-51B-1 became combat operational and flew its first sortie on 1 December 1943.
