Alright, well would it be able to do anything that the E model can not?
I'm not familiar with the specific specs.
Look at it similar to the Spit VIII and Spit IX. Slight performance differences, yet cover much different turf historically. Historically the N model covered the 43-45 time frame. The E's were gone for the most part as they were 41-42. In terms of scenarios, skinning, snapshots etc it would be much more historically accurate.
It was a better performer too. Don Lopez, who was an Ace in the CBI and later director of the NASM, said in his book "Into the Teeth of the Tiger" that the N actually performed better then the 51 at certain altitudes they fought at, and he flew both in combat.
The RAAF had over 500 N models. Again the skinners would be busy. The white tailed 5th AF P40s in general are all Ns. You want a natural metal P40? Gonna be an N model again.
