Another 1/48 Hasegawa P-40N
Hasegawa P-40N in the markings of "Island Dream" of the 7th Squadron, 49th Fighter Group, 1944.
The model is essentially OOB other than the aftermarket Aeromaster decals and the use of a vacuformed sliding canopy, so it doesn't sit "on top" of the rear glass area.
My experience of the Hasegawa P-40s, and I have built a few, is that if you take your time in fitting the various modular parts together, you will get a good fit, though you will still need filler, sanding and rescribing. Attach the rear fuselage parts to their respective fuselage halves before further assembly and you can work the joint from inside and out to get it as close as possible.
