[ForSale-Swap] Roller Inductor turns counter, dial, knob, etc

[Sandy and Kees Talen]

I have three knob and counter assys made by GE. The knob has
a crank and dial lock and is calibrated 0-9. The output shaft  is 
1/4" and one revolution of the knob equals one revolution of the 
output shaft. The second dial is calibrated 0-28 and one 
revolution of the knob causes one increment in the 0-28 dial.
There are no stops so the second dial really goes from 0 to about
38 in one 360 degree rotation, but the last 10 increments would
need to be marked. Internal to the knob is a gear set. Size is 
3-1/8" x 3-3/8".

Sure looks like a great antenna roller inductor control to me.
Pictures available. How about $45 each ?
