Isn't 349 a galvanometer ? I can se how I'd like it to be a motor, but
what's acting as the commutator ?


As I see it, either the off-center weight of the coil, or the
enamel is scraped off the contact wires only on one side. (I haven't
bothered saving the images and zooming in to see whether there is
sufficient detail to tell about the enamel.)

Enjoy,
DoN.

I'd say a motor myself. DC naturally.
