Anyone? No one here knows about these Columbia electric motors? I would be
shocked if that were true!

I saved the photo because I had never seen or heard of one.

Ron has a good point. Most of the early electric motors that were
used in the first electrified phonographs were of the "universal" type.
I seem to remember seeing this type in the early Columbia electrics.
Meaning they had windings of wire in both the armature and in the stator
magnets.
You should be able to figure out what connects to what with visual
inspection and a meter that measures continuity. Most of the old motors
went through some kind of resistance device, a long coil of wire on a
ceramic tube, for instance, as a way of controlling voltage. You may want
to submit
I know enough about them to use one to shock you...
But seriously if you can send a good bunch of pictures some of us might be able
to help. Wires and the location where they connect, jacks or connectors,
switches, any labeling or badges, etc.
