Hi
I might be able to shed a bit of light on 3T-S 420211. If my information is correct, this plane was flown by Lt Thomas C Vollenweider, my Fathers 2nd Cousin (my third). Thomas was killed over Bastogne on the 27th December 1944.
Here is a couple of links showing his was the pilot of 420211 when he was killed:

Unfortunately I am yet to discover any information on the nose art. If I do, I will post more information.
