Who made this motor? What was it for?

Looks like it's made to extend threads like this with all of us speculating on what it might have been used for.

Tesla model 3?

Looks like a little grinding motor for wheels at each end.

This is an Erector set motor.  You are missing the reduction gears.  The reduction gear attached to the worn gear side.  The reduction gear frame was attached using the 4 holes in the case.

I have several that came with an Erector set lot won at auction.

Thanks, it makes sense now.

Thank you for the picture. With the reduction gears, it is unmistakedly Gilbert......my personal failings are now exposed........not being mechanical, I lack the ability to extrapolate from a machine picture.

I only think in 2 dimensions. For instance, every layout I have ever designed is flat. I cannot envision anything with a grade.

That is why the collective knowledge of this Forum, so freely shared, is so valuable!

You can find nice sets on E-bay and at some of the train shows.

This one has a very good cord set, if the cord set is dried or crack it needs replaced.  Safety meeting of the day, this is a non-grounded metal items, that operates at 110 volts.   Be careful    Mike CT.

So were RW, A, S, R 1041 Lionel, American Flyer and Marx transformers!

I don't use metal cased transformers, and when the subject arises, I recommend that people set them side, and use a transformer with a plastic case.
I also suggest that cords be carefully inspected for cracks, including flexing the cord to see if any cracks develop.
And finally, I like to see all transformers used with external manual reset circuit breakers, or something similar.
