old model railroad electric trolley car (#2)

This one is a little larger than the other, and a 'one ended' design with a small cowcatcher at the 'front' end. Painted in an orange color, one electrical cable connector arm, lightbulbs and wire inside only, there is no motor. The bottom of this cast metal (I think) car is a piece of unfinished wood that the metal wheel trucks are also attached to, one of them has a wire going inside presumably for the lights.

No markings whatsoever, 'O' gauge I believe.
