This aircraft is indentified as P-40M on photo caption on "Red Stars". On the other hand there is a profile in this same book where this aicraft is drawn with new style rear deck of the cockpit behind the pilot and written as model N. Two numbers from the serial is weakly on show. "29". Tactical 93 is on US style font, and the whole plane, including red stars, is possibly painted in USA. No overpaintings visible.
AML has released decal sheet (P-40N)with "29" but nothing on the other side. Authentic Decals has released for this as model M and left side one can find numbers 354. The missing piece....? But if this aircraft is not model M either?
After closer examination this could be identified as P-40K-15. For example, the cooling grill plate between spinner and exhausts is missing.
Looking at the tail with some contrast added, there may be third digit after 28 (or 29?), possibly 2. What if the right side is 282?
Let's look if we can get any closer to find the digits on the left side. If the last stripped number is not 2, there are few more quesses. In all these cases, the serial visible on the left side should be 210.
