"Texas Longhorn" went to a Replacement Centre in Australia sometime in early Dec. ; Irvin ( "The Rebel" pilot) was sent home in Nov. 1942 so his E-1 41-25164 would have been available and flown by Landers at least once. Both in RAF camouflage; I think "Skeeter" no.81 was in OD/NG as she wasn't Lend-Lease. "Rebel" was no. 75.
Thought I should add this 7min. video of 9FS for those interested in P-40s in 1942, includes "The Rebel"; it shows the RAF camouflage on them ,and artwork / tail numbers.
