A fine Peter Gray manufactured switch lamp with a later cast body. It has the GRAY BOSTON standard top. There is a NYNH&HRR tag soldered under the lens on the door. The New York New Haven & Hartford Railroad seemed to use a lot of this model. You don't see many other roads with this Gray lamp. It's really hard to see. I think there is another Gray tag above that. Only Peter Gray used these flat targets. This is a yard lamp with 2 amber and two blue lenses. The ambers have yellow targets and the blue (ok, ok, it's lunar white) have white targets. There is a small punch hole in the very top. The sliding door works fine. I took the door off for some of the pictures.

Good
