It looks very nice. However, all P-40E-1 fighters received by the AVG were painted in standard Olive Drab, with Neutral Grey undersides. There exists only one color photo of the AVG P-40s, and they are all OD over grey. They did add the shark mouth to all of them, eventually if not initially. If I remember, I'll scan the photo for you. You can also find a not-so-great copy of the same photo in Osprey's American Volunteer Group Colours and Markings, as well as a color profile (#104) based upon the photograph.
EDIT: I forgot to mention that the individual aircraft numbers for P-40Es began with 100 (1 thru 99 being assigned to the Tomahawks). So, none would bear the number 40. I believe they reached as high as 127 before the USAAF took over on July 4, 1942. These planes did not carry CAF serial numbers like the Tomahawks did (IE: P-8115 and so on). They were identified only by the AVG numbers. Also, there were no new Disney Tiger decals available, so they would not have that on the fuselage.
