Set 2204 called for 44 pieces in the 35th edition catalogue of 1915. This set appears to be one that included only pearwood curves without a tangent line as it was described and depicted. Wood curves with tangents were offered individually as 2209. An April 1920 price list stated that 2209 would be discontinued when stock was exhausted. K & E main offices and factories were in Hoboken during this period. This product was typically used by in drafting table work by draftsmen, architects, designers, engineers and others.
