Pickett Manual for Model 3 Duplex Slide Rule

Pickett Manual for Model 3 Duplex Slide Rule

Usage conditions apply
This eight-page pamphlet, titled How to Use Model 3 Powerlog Slide Rules, is a supplement to Maurice L. Hartung, How to Use Dual Base Log Log Slide Rules (Santa Barbara, Calif.: Pickett, Inc., 1947). Hartung also wrote this pamphlet, probably around 1947. He explains scales not found on other Pickett models, namely, the extended square root, cube root, and tangent scales. Model 3 also had an extra log log scale (LL0).
This printing was made after the company moved to Santa Barbara in 1964. See the associated items, 1980.0097.01 and 1980.0097.05.
