This just in from Janice Bates, Ray Betcher's daughter, with regard to these questions:
http://www.electraforge.com/brooke/flightsims/b24_flights/questionsWitchcraft.html"He says the Collings Foundation did a good job of copying the colors on the plane (with the exception of the cowlings). The "3" on the number 4 engine was yellow and it was there for the top turret gunner to use to keep his bearings. "Q2" was light gray, the same color as the lower half of the plane. The tail numbers were yellow. The first 4-5 inches of the props were yellow, painted to be seen (in use) as a circle so people wouldn't walk into them!"
Looks like we are good to proceed.
If anyone has any other questions on markings or coloration, please let me know asap. Janice offered to ask any questions we have at the 467th BG reunion, which happens this upcoming weekend. Ray Betcher and another Witchcraft mechanic will be there, as well as Audre and her husband (John Kramer, I believe -- bombardier) and the man who painted the nose art on Witchcraft.
