Jim,

A portion of the shaft looks threaded, but the set screw knob is correct. 
It is even more correct if it is the same appearance as the other knobs, 
but has no white line on it.  It is unique in that regard.  You can always 
fill in the engraved part of a regular small knob and paint the knob, of 
course.

I don't have the mechanism in front of me, but if you have the manual, and 
the front panel down, it won't be hard to figure out any adjustments you 
need to make, provided the mechanism isn't broken with pieces missing.

You might actually need to screw it down fairly tightly to get it to lock 
the tuning mechanism.

Dan (Hank) Arney can be reached at hankarn at pacbell.net - I've bought a 
bunch of stuff from him, including his reproduction R-390 covers 
(top/bottom, RF deck, crystal deck back panel cover, R-391 tuning knob 
locking pins, tags, R-391 tuning chart, green gears, powder coated tuning 
knobs, powder coated front panel, and more).

You'll have to check with him to see what specifically he has in stock, of 
course.  As far as I know, he does all the stuff himself or farms it out. 
All is top notch quality.
