A square-bodied, pin mount switch lamp probably shop made by one of the New England RRs. There is no mfr hallmark or railroad markings noted. "2244" is stamped on the sliding door near the top. The lamp has two signal green and two amber lenses, all in good shape. The fount/burner unit is intact. The chimney cap is slightly bent. The entire unit shows old flat black paint, probably original. This is a nice old lamp. Condition: (8.0). Dimensions: 6 - 1/2" x 6 - 1/2" x 15 - 1/2".
