The key to all this is whether we get any other variants beyond the E model.
If not, then will skinning Merlin 40s and P40Ns be allowed on the E model?
I for one hope we have more variants so the skins can be placed on accurate models of the 40. Just looking at all the P40N profiles available speaks to this. All those white tail, star and bar PTO 40s are N models too. E's were gone by that time.
