Well, if you're looking at it that way, then you could say mk IX airframe was esentially modified mk V airframe which was modified mk II which was improved mk I, which again was based on 1936 prototype.
That said, Me 262 is based on 1941 airframe...
Look at it this way -
Merlin 266 = Merlin 66 made in the USA. (2 denoted manufactured abroad)
LF IXc (1943) had a Merlin 66
LF IXe (1944) had a Merlin 66
XVI (1944) had a Merlin 266
Identical planes APART from 1 difference - The XVI and LFIXe had 2 x .50cals.
Both the LF IXe and XVI rolled off the same production line, side by side.
All that decided the mark number was where the motor was made.
Urchin hit it on the head -
"There is a reason that the Spit 16 and La-7 are the most used planes... they happen to be the best planes for the game."
XVI was made for low alt fighting, guess where most of the MA furballs are?
So you can say 50 cals makes it 1944, but then again people argued the old Mk IX was a 1944 bird for the same reason, despite it having a 1942 Merlin 61.
To be honest, I would bet the VAST majority of kills are to the 2 x hispanos anyway.
