I've got a few of them, and like the ones made by Nutone most of all, partly because they use Telechron motors. Some others also use Telechron motors, like some made by Rittenhouse. But this one seems pretty interesting because they used not just the Telechron motor, but the whole clock, which happens to be a 7F57, just slightly modified for use here.
It has the most heavy-duty chime mechanism that I've seen, with an industrial-looking 110 volt motor with gearbox to drive the chime camshaft. I think it could have been done more simply with a Telechron B3 motor, or a type C motor if more power was needed.
The patent that covers this chime was awarded to F. B. Little of Chicago. He received other patents that he assigned to Deagan Chime Co., but this patent isn't assigned to any company, so it's unclear whether it was made by Deagan or not. A similar unit was shown on the Eureka-Modern website a few years back, and later on the Knock Doorbell website that is operated by the same person. The Eureka-Modern/Knock Doorbell chime included chime tubes marked "Deagan". That doesn't prove that they also made the complete chime unit, but they may have. Mine didn't come with tubes, so I'm going to substitute Herschede tubes with the same tuning.
Attached are a few pictures.
