Ok, you made a stang, you made a 109, a 190 a b17, etc.
If it were up to me, when I did the plane, I would go ahead and make the full war variants.
Right now, you got late war only, but the plane is there, just tweak the numbers and make all the variants.
If the artwork is the hold up, pluck it, use the same stuff, just diddle the FM and loadouts.
