"Not the Merlin 61 Spit IX, which is what AH has."
CT setups will never be so detailed as to assign subtypes based on the exact engine or fuel. We dont have the planeset for that, and probably never will.
The "E" wing Spit IX and Spit XVI were used untill April 1945, so it may not have a Merlin 66 but it has the right armament, so I guess it all comes out in the wash.
Like I said, its not required, just a comment.
There were no 109G2s or 190A5s flown by the LW in 1945, but I have no big objection to them being included other than it takes some of the "atmosphere" away. They had 1000's of 109G-10, 190D-9, 190A-8, and Me 262s being produced monthly, all brand new...the shortage was fuel and pilots, not airframes.
