AC current motor driven mechanical clocks.
I have gathered a decent collection of these over the years,a few are from the '30s and need a spin to start the synchronous motor. Lots of different motor designs and brands before the '90s. Telechron started in the '30s and went to about 1993. I think the only company still making proper electric clocks for commercial use is Electric time and i do not know who makes the motors. Several school "slave clocks" are in collection and those are often 24v. About 1980,drug a big one out of a junk heap-about 15-16" dia, heavy brass mechanism,motor had two big field coils with green cotton insulated magnet wire: at the time i thought it was very old -probably from about 1930 - but later recognised it was more likely from about 1915...Oh how i would love to have that back and restore to running order
I have looked around and not found another like it,it might have been made by Western Electric .
