An earlier member of the Curtiss fighter family. The Lindberg 1/48 scale Hawk in Nationalist Chinese color. I repainted an old kit that was in USN yellowing but showing its age. .
The P-36 had a variety of armaments including one .50 if mounted in the nose. The P-40C had .50s in the nose and .30 in the wings. The P-40E had six .50s.
The model you have made has the cowling associated with the Curtiss-Weight R-1820.
US Army Air Forces P-36A and C were powered by Pratt & Whitney R-1830s with a more closely fitting cowling with prominent blast tubes for the nose guns.
