Hey there Pongo! That is ONE OF OUR BIRDS! THE
325th FG "THE CHECKERTAIL CLAN" 15th AF.
To answer your question: # 77 was one of the birds of the 319th FS of the 325th FG. The "Checkers" were on the upper and lower wingtips as well as the upper and lower tailplanes.
Some of the later war birds even had checkers on the drop tanks and gear doors.
She is a REAL beauty, wish we had those colors in here!
