I found this at the site of an old carbarn and was wondering if was part of a trolley traction motor...can anyone identify this piece? I'm 90% sure it was something trolley related since it was at the site of a carbarn...
 
This is it, it's old an dirty...if you have an idea of what it is please reply.

Bryan -
I see no takers on your question thus far.  I  did spend some time web surfing looking for old trolley diagrams, similar parts, etc.  So far nothing.
 
Hunches have included some kind of electrical coil, dynamo coil, etc. Do you have a side view?  And can you provide a size?  Say, a photo with a ruler next to the object.

Charlie, thanks for the response and the web surfing. I tried looking for diagrams on the web but found nothing. Here is another view...I'm not sure what exactly is the 'front' and 'back', but here what I call the 'back' of the object.

Looks to me like the spring from a trolley pole retractor.

I vote for the spring identification. It has the same appearance, only larger, as a wind up watch spring.

Thanks to all for your input and guesses. After reading your responses about it, I'll come to the conclusion it is the spring from a pole retractor...now to only find out which car it came from

It is a helical spring which would have been mounted in a housing attached to the rear of the trolley car. when released it would hold the trolley pole in contact with the overhead wire. When the pole was lowered by means of the rope mounted to it and hooked in the down position the spring would be "wound up".

I'd reverse the direction of the spring's use, it either kept the trolley pole rope tight in a catcher, or pulled the pole rope down into a retriever after the pole came off the wire by accident.  In the 2nd case, there would be 2 springs, the other would perform the 1st function.
