Hi there. I am working on reverse engineering a an assembly drawing into CAD. This part has a couple bends and a call out that I have never seen. Anyone know what this is telling me? images attached.

Yeah. Lots of older stuff was done like that. I spend a lot of time updating prints from the late 30's to the late 60's.
14 in 84 means... 14inch rise over an 84inch rise... assuming those are inches. They probably had a machine or jig with a base of 84. See it a lot for lathe turned parts based on 12"
So trig it... tan^-1(14/84)=9.462 degrees.
Also looks like it only applies to items 69 and 85
See attached pic... looks close enough.
