No worries, mate!
Further personal criticisms are the wheel wells are too shallow (I cut them out and set them them deeper), and the cockpit a little sparse, with a bad fit around the instrument panel, but the canopy is the thing that's really noticable.
In saying that, panel detailing is superb (as usual) with only the starboard side rudder needing to be scribed. The engine is superb, and if you add the cylinder hoses really looks the part.
Re the P-40K,it appears to be a K-15-CU or K-20-CU, so if you want to convert it to an M (just add the cooling plate ahead of the exhausts on both sides, and 'Voila!' ) then I can give you markings for an RAF, SAAF, USAAF or RAAF aircraft if you like. ...or you could make a kiwi K-15/-20-CU or M Kittyhawk, although I don't have any spare pacific roundels unfortunately.
