    There are collectors for everything, Joseph, but Google would be a better place than ModernMechanix to find them.

    As I write this there’s one going for less than six bucks on eBay another for $20.

    Excellent link, Firebrand. I’m saving that one.

    The dial Addometers are right up there with the Curtas for style (if not technology – didn’t Pascal invent this?)
