This one has had no tries in a few months ...
Since Dick Phillips is the master of hard-to-solve P-51 Who? cases, it is time to step in and give some hints.
This P-51 is flying today. This P-51 was flying in WWII ETO with the 357th FG and carried the same paint job years back. The "N"number a few years back carried the last 5 digits of the serial number.This P-51 now carries the paint of a 361st FG P-51.
It should be easy now (too easy).
Hi Santa,The deniable Mustang on the picture could be4 4-63810, P-51D-20NA, c/n 122-31536 With 357thFG during WW2 as Stump Jumper B6*C, On display for many years, rebuilt to flying condition in 1972, registration was N63810 for some time, and the aircraft was painted as Stump Jumper. Now registered N451BC, "Angel's Playmate".
Martin (Swiss Mustangs)
I agree with Marc Koelich - only note of interest is that this a/c also flew with the 167th FS WV ANG (The 'Coonskin Boys') and carried the nickname 'Stump Jumper' (plus a painting of Woody Woodpecker) there, too !
OOPS! You guys got this one right, but I overlooked it at the last update. Good Work.
