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...
