The F and L models are largely Rene's work based on Mike Wholaver's P-40F. We don't have the source file, and the only existing P-40N that I'm aware of is the Firepower one, which is also by Mike Wholaver, or at least, based on his F-model. So I'm not sure we can do that one as it stands, although I suspect it has crept into RS unnoticed...
There are actually 4 separate versions of the P-40E as well. Details... If you know what to look for, you'll have spotted that already, and you can probably guess the other two. Clive has done a splendid job.
Next project is a rework of Dancat's E-model into a P-40K Kittyhawk III. I don't think he did do a Tomahawk - or at least, I haven't seen it.
