- Description
- In the 1950s, several manufacturers sold inexpensive plastic slide rules for use by students. This one-sided, ten-inch example, sold by the Chicago firm of Dietzgen has K, S, A, D, T, and L scales on the base. B, CI, and C scales are on the slide. The rule has a clear plastic frameless indicator with a hairline and black plastic endpieces. The top right corner of the base is marked: NATIONAL. Both ends of the slide are marked: DIETZGEN (/) NO. 1767. Both ends of the bottom of the base are marked: MADE (/) IN (/) U. S. A. A cream-colored synthetic leather case is marked: R. LAWSE. The rule was received with an instruction manual, 1988.0367.02.
- According to Peter Hopp and Bruce Babcock, Dietzgen manufactured model 1767 from 1955 to 1959. An earlier version of the National, the 1767P, had a different set of scales. It was manufactured from 1941 to 1952 and sold in 1952 for $1.75 or $18.25 for a dozen.
