A stylus hexadecimal adder.
I've never seen one of these before.

Very interesting device Don, thanks for sharing this. As I see it is now sold, did you get it? If so, I'd love to see some notes about how it works, etc. once you've explored it.

No, I saw it on "completed" listings. Somebody else got it. But I don't think I would have paid that much ($50).

Hi Don,
I've never seen this one, but I seem to remember having one that was like a circular slide rule. I did some googling and came up with some references to the original company and some additional info on the HexAdder.
Original company is still in business:
HEXCO, Inc
Museum reference (another rabbit hole to go down):
Southwest Museum of Engineering,Communications and Computation
David's Calculating Sticks
National Museum Americal History
