degree worm gear on the base.
it was in terrible condition when i bought it but it cleaned up well.
still trying to figure the date on that one....must have been early 50's as i still have not seen another.
has anyone seen or does anyone have one of these rare unitron 140 mounts.
notice the worm gear on the base...it dosent run out
of travel like 99.9% og the others i have seen.
here is a before and after picture.
