Manufacturer: K & E
An exceptional K & E slide rule with a hard leatherette case for your appraisal & appreciation.
The slide rule is beautifully preserved mahogany wood with off-white facial & both sides of the slide. (My photos just do not do it justice.) The core of the slide is also mahogany. The face of the rule is marked "KEUFFEL & ESSER CO. N. Y. PAT. 1.934.232 MADE IN U.S.A." The slide is marked "(4056)".
The backside of the rule contains Equivalents & Abbreviations & Settings. The backside of the slide is marked "806463".
The slide moves properly & the sliding window also moves properly without being loose.
The rule is in as excellent condition as could possibly be.

The backside does have a 3/4" square patch of Scotch Tape with the name "HALL" written in red.
The slide rule fits it's case perfectly. The leatherette case has a faux moose leather pattern & has markings on the lid portion "K & E FAVORITE TRADE MARK SLIDE RULE 4056". The corners of the case show wear although the slide rule shows no wear.
We believe the slide rule is one of the earliest models & hence dates to the early 1900's. It would be a superb addition to a collection of slide rules or mathematical devices. Thank you for shopping at The Treasure Chest. Item ID:AA-17) |
