 More of my dad's estate:  Lot set of four identical: Beckman Helipot Duodial Turns-Counting Dial.  Model RB, with max 14 rotations.  They were opened for inspection to confirm still working and complete then for photo's only.  NOS.  Are designed for use with the  Helipot precision potentiometers models A, C, 7601,9301,7216, & 7246.  Please see the photos for the detailed spec's. Not sure who needs these but they are of fine quality and for very tight tolerance uses. They are not simple knobs but have a mechanism inside to advance the counter. These things weigh in at 32 grams each. Check out photos to confirm operation. All work fine and move smooth as butter with the subtle bump at each of the increments.   High quality for yard sale prices. Please see the "list of Countries I do not ship to", below. USPS small box priority is cheapest most everywhere but ask if you must. PayPal is preferred, please.
