If your point of interest is in fact the plane seen in the graveyard in BYOOL, based solely on the name I would suggest that it is one of the two aircraft that flew with the 351st. Both were B-17 Fs as seen in the screen cap.

Don't know if I can post pictures...there is a link to the film sequence below.
According to Baugher's excellent reference page 5823 returned to USA in June 1944...went to the RFC at Ontario (convenient to Hollywood) in May 1945.
A plane by the same name also flew with the 351st and was salvaged in June 45--apparently overseas.
It would be unlikely that both planes by the same name flew concurrently in the same Group and Squadron, so it could well be that--the evidence being what it is--the plane in the movie is 42-5823.
Lockheed/Vega B-17F-25-VE Fortress
42-5823 (351st BG) returned to USA Jun 1944. To RFC Ontario, CA May 7, 1945
42-6151 (351st BG) salvaged Jun 11, 1945
If you want to see the whole graveyard scene, it is here:

It is my opinion that the nose numbers are RFC stock numbers and have nothing to do with the s/n or c/n of the plane.
UPDATE/EDIT: 42-5823 was apparently reclassified as TB-40 and posted to Yuma, AZ gunnery range. It appears to have sustained Cat 3 damage from a Friendly Fire shoot down on 20NOV44.
