Looks like years after my initial post I have an ID for the aircraft he was on.
A site dedicated to busting military posers, Valorguardians, does a Valor Friday story and Lt. Femoyer was the topic today, and his aircraft is listed along with its name and nose art. I was floored, I had given up on ever figuring it out, and there in the story is all I had seeked.
It is or was a Douglas-Long Beach B-17G-25-DL, 42-38052, "Lucky Stehley Boy” (Aircraft doesn't show up under Joe Baughers site). The aircraft was later involved in a landing accident, repaired returned to service and survived the war, only to be scrapped. There are two additional pictures on the link, showing the landing accident, coming in with only one main gear down, and a shot of it after the landing.
The veteran bomber was flown back to the United States and on 15 August 1945, arrived at the reclamation center at Kingman, Arizona. It was scrapped 8 November 1945, after less than two years of service. 42-38052 was a replacement aircraft and was flown by several crews. It carried the names El Mal Centavo (“The Bad Penny”) and Lucky Stehley Boy.
A Google search turns up so much more information now, than when I started this search 13 years ago back in 2008.
