The nose profile is based on the P-40B side profile. Obviously the cross section of the Corsair is circular and won't match up with that of the Tomahawk. So I shaped the nose from a block of resin from scratch. The Tomahawk exhaust stacks looked silly, so I tried 2nd stage Merlin exhausts, which looked okay. The Hurricane exhausts looks the best. I'm almost sure I've drawn a profile of a turboprop one? If I find it, I'll post it some time.
