B17 wooden ammo boxes

[B17restorer]

I am looking for manufacturer drawings for the .50 cal ammo boxes used on B17s during WWII. I have a partial picture of a drawing for a cheek gun box, drawing number 15-13853. I do not know if it is a Boeing or USAF drawing. Does anyone know of a source for the drawings?

There is a forum member, Dragonflydf that has worked on B17 restorations, I'd try him. http://www.jouster.com/forums/member.php?3138-DRAGONFLYDF
