This 10" duplex wooden slide rule is coated with white plastic and has a glass indicator with a metal frame. One side of the frame has DF, D, and L scales. The other has A, D, and K scales. One side of the slide has CF, C1F, C1 and C scales. The other has B, T, ST, and S scales. The instrument fits in a leather-covered case with a leather flap at one end. This, in turn, fits in a yellow box that also holds a set of conversion tables copyrighted in 1950 and a pamphlet with instructions for care and adjustment copyrighted in 1952. An instruction manual copyrighted in 1954 and a warranty also came in the box.
The model 1746 is not listed on a 1943 Dietzgen Price List. It is listed in Dietzgen Catalog 22D (1948) and in the 1953-54 Dietzgen School Catalog.
This example of the slide rule was owned by M. Gordon and Marion Tiger. Mr. Tiger worked for the U. S. Department of State in the 1950s and 1960s.
