Good Job,
from what I know
the BF109 skin
I know that they the model is different in the early version (Nose is a lot different)
I guess that they are the same from the Variant F-2 and onward.
the P40
the variants B and C are much smaller so the Nose skin will appear on your Tail (I tested this with a Different skin)
B25 skin:
there are a lot of B25 variants but only one is the Playable so just paste them in all of the B25 folders
going to download as soon as I finish work.
Thanks Dowly
