Pickett Model 4 (2) - Notes



  1. This is one of the variants of the Model 4 by Pickett. I have noticed that there are a number different scales and layout in other versions of this rule on the web. This also applies to other early Pickett rules as if they were playing around with the design on a regular basis. This is understandable as the Pickett rules were not 'engine divided' but printed on a standard rule base so making new versions of a rule after feedback from customers was probably easier and therefore a more normal practice for Pickett in the early years.
  2. Refer to Model 4 (1) for another version of this rule with a slightly different layout and scale changes.
