Pittsburgh trolley or train part?

[GoVidGo]

I was detecting in a Pittsburgh park, almost downtown in the main city, which runs along an old, and still used, train track. There were also trolleys that ran through Pittsburgh.

I found this bent plate. It might have got hit by a lawnmower or who knows(?)

The plate has street names under each of the slot openings. Different ones on both sides. Down the side of each plate is also stamped 'S O & C 1174'. I tried to get some good pictures as well as one next to a tape measure so you can get an idea of the size.

Could this be off a trolley and have anything to do with the stops and streets? part of the controls? maybe a display? Could it be off a train?



Thanks for the help, in advance!

Info below is about a company in Ansonia, Connecticut. Perhaps the wrong company but the only one with the same initials I could find.

This is a little info about the S.O. & C company.
In 1882, as an offshoot
of the above named company, there was incorpor-
ated the S. O. & C. Co., which has since been en-
gaged in manufacturing eyelets and eyeleting ma-
chinery, and also metal goods.

It is a very large page and you will need to use the 'find' feature(Ctrl+F) in your browser to search for S. O. & C. Co, there are several other references to the company too. It's possible that this is a different company than S. O. & C on your item.


Another SOURCE mentions this of the company....
SO&C (Schneller, Osborne & Cheeseman Co.), a brass trimmings company.

Good luck with the ID, I can't think of anything it could be for any practical use.
