Description
This small, one-sided sterling silver slide rule is in the form of a tie clip. It has A and D scales on the base and a C scale on the slide. A clear plastic indicator has a red line and is in a metal frame. The back of the clasp is marked: VERNON. It is also marked: STERLING.
The donor recalled that he obtained this tie clasp from Edmund Scientific Company. The 1965 catalog of the company lists a tie clasp with a "silver oxide" finish that cost $2.00. The 1971 catalog lists a tie clasp with a gold finish that cost $3.00. However, these tie clips had screws in each corner, while this example has no screws.
