Pickett Model 3 - Notes

  1. 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.
  2. 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 This was superceded after 1950 when the new cursor type was introduced which makes this rule at least 50 years old.
