Keuffel & Esser N9081-3 Doric - Notes



  1. This rule is part of the Log Log Duplex Decitrig family of rules.
  2. The scale configuration on this rule was introduced in the 1949 catalog and was no longer listed by 1955.
  3. For a "plastic" rule this model has a wonderful feel, not quite as heavy as the equivalent 4081-3 it still seems to feel more solid than other plastic type rules.
