Vintage Engineering Instruments 250-V Slide Rule. Good Condition. This ten-inch, one-sided wooden slide rule is coated with white plastic on the front face and both sides of the slide. A, D, and K scales are on the base. B, CI, and C scales are on one side of the slide, with S, L, and T scales on the other side. The indicator is clear frameless plastic. The top of the base is marked: MADE IN U.S.A. It is also marked: ENGINEERING INSTRUMENTS, INC., PERU, INDIANA. It is also marked: PAT. PEND. The right end of the slide is marked: 250-V. Tables for equivalents and conversions appear on the back of the instrument. The rule fits in a tan paper sleeve—neither the original simulated leather case nor the instruction manual were received with the instrument. The rule probably dates between the late 1950s and 1967. The model number may mean that the rule is 250 mm long with a veneered finish, although the scales are actually about 255 mm. Vivian (Breyer) Lawrence received Lawrence Engineering Service, a manufacturer of slide rules in Peru, Ind., in her divorce from George Lee Lawrence in 1947. Her new husband, Frank Bozarth, was president of the renamed Engineering Instruments, Inc., until the company burned down in 1967. Although the building was insured, Engineering Instruments never rebuilt. We are a Top Rated Plus eBay seller and stand behind every item we sell.
