Saw this today at a flea market here in NY, with a local vendor. He didn't know where it came from though. Who had this style of signal, Erie? NKP? It weighs about 84 tons, so I couldn't pick it up to see what manufacturer might be marked on it. But it appears to have been removed and discarded with the guts inside. I don't think it could be PRR, B&O, NYC, or LV.
No idea what this kind of stuff is worth, either.
