I just received my Sperry Buddy the other day, and wanted to let you know how cool I think it is! The lights work great, especially the front/rear selectability. I'm a retired NY Subway Train Operator, and Sperry did frequent inspections using a New Haven Mack RailBus from the '50's that was small enough to negotiate the tight curves & tunnels. I managed to get a pilot job on it one night in the late '80's.
Item shown is recently purchased RMT-92510-2 SPERRY #101 RDC/BUDDY.
