The product is a vintage blue and amber glass lens signal lamp designed for railroad use. With a 5 1/2D 1/2FID measurement, this item is a classic piece of transportation history. 1 blue and 1 amber lens. Perfect for collectors of railroad memorabilia or enthusiasts of lanterns and lamps, this piece captures the nostalgia of a bygone era in transportation. The amber lens has a small nick on the front as shown in the pics as well as an edge nick on the back, the blue one has a ding on the first ring from the center, the glass is still in tact and did not pop out. I also feel some very smell little nicks on the front. Please look carefully at all the pics!
