WANTED: AN/RT-18/ARC-1 Fine tuning thingy...
 

Hi,

I know I could easily make one out of a knob, a piece of steel
shafting, and a brass gear, but I would prefer the real thing.

So, does anyone have a spare fine tuning knob for the ARC-1?

Also is there a pdf of the manual out there somewhere?

Thanks!
