content: This long, relatively thin transparent plastic curve has a single relatively narrow opening in the bottom half. Similar but not identical curves were sold by Dietzgen and by Keuffel & Esser Company. Dietzgen assigned the curve number 18 (part of catalog entry 2152 in the 1926 catalog), while Keuffel & Esser gave it the number 20 (part of catalog entry 1860 in the 1921 catalog). A mark on the object reads: 22. In its 1883 catalog, James Queen and Company listed a similar curve made out of hard rubber as catalog number 653, #22. However, it does not list plastic curves in this catalog. In a 1922 catalogue, Queen lists a curve very similar to this one as number 22. It cost eighty cents in pearwood, one dollar in rubber, and $1.20 in celluloid.
