help idendify this steering box

heres the numbers on it:AA 17
68 3580
also another set of numbers
AA6
48 3550

 

Kind of blurry to me but I'd say a ROSS. Don't know what it is off of.

 

Ross is my guess...

 

Nope.
Is 1936 Ford...
The "48" number is the case, same '35-6, the "68" number is the sector cover, 1936 only, differing from 1935 by roller bearings fro sector shaft.

 

Smarty Pants...

 

Bruce: Does that mean my assy is a '35 since it has a "48-3550" case and a "'48-3580" pitman shaft housing?

 

Yup. Oddity 101: Innards are apparently same in general as '32-4, but backwards...so if you need to be able to reposition a pitman arm by 180, here are some tools! Also great for pranks!
