Pickett Model 3 - Notes
|
|
|
|
- There appear to be two variations of this model, this one the Deci-Multiphase Log Log and the
Deci Log Log Vector. The differences appear to be the scale arrangement.
- This is an old style Pickett with metal cursor pieces. This was superceded after
1950 when the new cursor type was introduced which makes this rule at least 50 years old.
