I've got basically the same machine from Wiscojim who lives in Appleton and knows the person that built them. I was able to get mine working though it's been sitting a while and the mech may need a going over again. These were basically background music systems for restaurants and similar businesses, the company made some jukebox versions of this mechanism, some that would play both sides, and eventually sold the design to IIRC Seeburg who kept it in production (techmoan on YouTube has one of those).
I'm sure Jim will chime in with some interesting information.
