Just got this one and not familiar with the fine tuning control, the knob is missing that apparently drives the fine tuning, all I have to go by is Rider,s and it does not show the mechanical hookup. Need help figuring out how it is suposed to work and getting a knob.

I'm pretty sure the vernier drive on this model is a coaxial ball-bearing planetary, so there's no "hookup" visible. http://www.renovatedradios.com makes repro inner and outer knobs.
