General Railway Signal GRS Railroad Light - Semaphore Antique Rear End Marker For Sale

This seems pretty unusual I could not find another one like it. The guys told me this is probably a rear-end marker or a semaphore light. I will let you decide. I would guess it was a rear end marker. Overall I\'m very good condition. I see no reason for it to be broken other than the bulb is probably no good. Runs on 12 volts but I put my phone on the inside to illuminate it. Rare, hard to find. Thank you for looking.

Stands about 12 in tall and 9 in wide.
