old model railroad electric trolley car (#1)

This model trolley car appears to be complete, and also appears to be completely unmarked. Maybe somebody will know what it is??

It actually does have a motor inside it, along with little lightbulbs and wiring. Painted green with red doors on each side at each end that don't seem to open. Both ends of the car look the same, both the little movable electric cable connector arms on the top seem intact and as they should be. Wheel flanges are 1-1/4" apart, I think that makes it 'O scale'.
