Mitchell,

You have this file listed as a P40b. The model in the photo is definately a
P40D, or later, variant. The easiest way to tell (head on) is the shape of
the air intake above the spinner. The P40 A-C had a round air intake, while
the D and later varients had a flattened rectangular air intake opening,
(some P40 varients had no air intake openings above the spinner at all).
