      charmsomeone, Cool. :-)

      Boy, when I ever saw those patent numbers listed on the back (2697981, 2707432,
      2826140, and 2928336), I thought I'd hit some serious patent pay dirt.

      Well, apparently the subtleties of the Canadian patent database escape me, because none of them turned up anything similar to a Paymaster machine.

      I won't bore you with all of them, but the first one was interesting, because it turned out to be for a Blackberry. Yes, that Blackberry:

      https://www.ic.gc.ca/opic-cipo/cpd/eng/patent/2697981/summary.html

      So, back to the drawing board. I did a key word search, and that was more promising. I figure one of these is close, anyway:

      https://www.ic.gc.ca/opic-cipo/cpd/eng/patent/2026964/summary.html

      https://www.ic.gc.ca/opic-cipo/cpd/eng/patent/2200503/summary.html

      https://www.ic.gc.ca/opic-cipo/cpd/eng/patent/2165588/summary.html

      Here's the real deal:

      https://www.madeinchicagomuseum.com/single-post/paymaster-corp/

      Then there's this:

      https://www.icollector.com/Paymaster-Series-X-550-Cash-Register_i19602988

      Which the vendor described as a "Paymaster Series X-550 Cash Register" (um, no), but fortunately, this one has a USPTO patent on it (2697981), so:

      Well, if I'd started off with the USPTO, I would already be home. So to speak. };-)

      Those patents listed on your machine are all US patents, grant dates ranging from 1954 to 1960:

      https://patents.google.com/patent/US2697981A/en

      https://patents.google.com/patent/US2707432A/en

      https://patents.google.com/patent/US2826140/en

      https://patents.google.com/patent/US2928336A/en

      Still, I hadn't gone fishing in the Canadian patent database, I wouldn't have caught the patent for the Blackberry "METHOD, SYSTEM AND MOBILE DEVICE FOR IMPLEMENTING A SERVERLESS PRESENCE SYSTEM."

      Man, that's a mouthful.
