DescriptionRailroad Pen 5-1/4", probably model 976-2, sold by the Keuffel & Esser Co., N.Y., no date, circa 1930-1950 (possibly earlier than 1930.) Hollow handle with two pairs of nickel silver curved spring blades with three adjustment nuts. Marked on ferrule of handle above rules: Keufel & Esser Co. Germany. No other product marking. Two each with varying condition (some rust and the original black finish on handles is generally worn off) and slight differences in details and length. Other common name was curve or ruling pen. These models were probably in the Anvil trademark line and are close to the model 932. K+E general offices and factory were in Hoboken during the period when this item was made. While these items were not made in Hoboken, they are typical examples of the imported products that were stocked and shipped by K&E.
