Parts for Pickett Slide Rules

Here is a table of Pickett slide rule part numbers we can supply. Be careful; models with and without the "N" prefix take different parts. However, the suffix "T" ("true color" white) or "ES" ("eye saver" yellow) merely denotes the body color of the slide rule; it has nothing to do with the physical dimensions of the rule. Ignore the T/ES suffix when determining part numbers.

Parts for Relay and Ricoh Slide Rules

The Relay Industrial Company (also know as "San Ai Keiki") was the second largest manufacturer of bamboo slide rules in Japan after World War II. The company was purchased by, and the name changed to, Ricoh in the 1960s. Relay/Ricoh bamboo slide rules were marketed under various brand names including Alvin, Compass, Dietzgen, Engineer's, Jason, Lafayette, Lutz, Micronta, Olson, Pickett, Relay, Ricoh, San Ai, Sans & Streiffe, SIC, Skyline, Wallace and Wallace and others. They frequently did not carry any Relay or Ricoh identification and can be difficult to differentiate from Hemmi-made bamboo rules. There are two sure ways to tell a Relay/Ricoh bamboo rule from a Hemmi rule: 1. R/R bamboo duplex rules always have plastic cursor lenses whereas Hemmi bamboo duplex rules always have glass lenses. (This doesn't help identify the manufacturer of closed-body rules; both manufacturers used both glass and plastic on their closed-body rules.) 2. Hemmi rules always carry the Hemmi brand name somewhere--sometimes just stamped into the cursor. If it's not marked "Hemmi" somewhere, it's R/R.

Quantities are limited (sometimes only one). Email us if you need something not on this list or if you're not sure what you need.
