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 Bill Smithville, NJ |
