There is a green leather case with white inlays on the holder for the flap. The flap is marked: K + E. Inside the flap is written in ink: Jeffery (/) Smith (/) P 68. An orange chamois case holds a magnifier with two lenses and a metal frame. On one side, the frame is marked: K + E. On the other side, the frame is marked: PAT. NO. 2556806. A green cardboard box, missing one end, holds the rule, its case, the magnifier, and its case.
For information on the patents on the rule, see 1993.0482.01 and 2007.0181.01. Paul E. Gaire of Manasquan, N.J., received a patent for the magnifier in 1951, replacing his earlier attempt at a magnifier, which could only be used on one side of a slide rule at a time. This double magnifier was first advertised in Keuffel & Esser's 1954 catalog and first pictured in the 1962 catalog; it sold for $5.50. K&E sold this version of the model 4070-3 slide rule from 1952 to 1962, at a price of $20.50.
