Over the weekend we acquired a Ford Industries Code-A-Phone 700C in excellent condition for the house, which we plan to connect to our PBX as an answering machine. It even came with a tape! Unfortunately, the belt that drives the rewind seems to have lost since it won't rewind on its own without a little help. I'll have to open it up soon and see what I need to replace the belts. It plays though! Ours is a 700C made in January 1981, with the serial number 0615 (???). A shockingly low serial number given how late this was made, seeing as the Code-A-Phone 700 had been on the market for 15 years at this point. (any vintage telecom experts have ideas?) There's also a Communications Canada sticker with what I think is a certification number, but can't find any results for it. I'm guessing this unit was sold in Canada and somehow made its way to the US later in life; it's also lacking the Bell icon that The Connections Museum's unit has. Ours just has a white plastic plug where the Bell logo appears on most other examples of the Code-a-phone 700 (https://twitter.com/museumofcomm/status/1524450698548580352).
