Vtg Dietzgen Clearcite Radius Curve Set Wooden Box 2258 Drafting with 54 Pieces. This set includes 54 acrylic plastic curved drafting curves in a wooden box with dovetail edges.

Box closes with two hook latches. The top of the box has a label from the State of Colorado, Dept of Highways, which was the original owner. The box as well as the curves are marked R. Possibly ROW is an acronym for a building, and the box was kept in room 34, but ROW could stand for Right of Way. The set was made by Dietzgen in the USA. We are a non-smoking house, but we do have cats.
