I have the decal set for Geronimo (+ 2X RAAF birds … errr … kites) on the sheet I got for the 80th FG P-40N. If you are interested, let me know. As far as I can tell the Ns were the only variant to get the 27inch wheels (also first batch (N-5 ) had only 2 .50 cals per wing. to save weight to improve high altitude performance. ) Later Ns went back to 6X .50s , not sure if they still got the small tires. E-M should have the “standard” 30 inch tires.Look like the rims were same size for E-Ns (B-C-D?) Most photos I’ve seen show the E-Ms with the covers (same for B-C-Ds)
