[Amps] Turns Counter

[dd3ly at arcor.de]

Hi,

I have a few turns counters left which were manufactured by (or for?) Collins Radio. 
At least they carry a Collins Part No. and they look very similar to the knobs we all
know from Collins gear like 30L1 for example. I will drop a mail with a few pictures
if you are interested.

These turns counters have just a knob, not crank handle. They count up to 20 full
turns (of 360 degrees) and then they start again with zero. They are VERY easy 
to mount into a front panel: You simply drill one hole like you do when you mount 
a potentiometer. Then you put the axis through th hole and fix the turns counter 
with a nut, just like you would do with a potentiometer.

I have a small quantity for sale, more than I will need...
