Keuffel & Esser N9081-3 Doric - Notes
|
|
|
|
- This rule is part of the Log Log Duplex Decitrig family of rules.
- The scale configuration on this rule was introduced in the 1949 catalog and was no longer listed by 1955.
- 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.
