Some over on the "discussion side" of this board was looking for manuals for a 9U late so I went out to the shop to see if I had any. Not the ones to help him but I did have for earlier 9U's;

Ser. Ref. book D-6 4U,5U,8U,9U
Parts book D6 9U 1 - 13262
Op man D-6 8U,9U

So, since I had dug'em out thought I'd list'em and see if someone else could use them
A bit dirty on the covers but clean and complete inside
$50.00 + shipping for all three
