Pickett 931-ES - Notes
|
|
|
|
- This rule was specially made for the Capitol Radio Engineering Institute.
- Identical to the N531-ES in the scales. This rule appears to be older
as it does not include the N prefix for the model number. It is also a narrower rule being based on the 900 series
body rather than the wider 500 series body.
- Pickett has a history of making special rules for organizations or as advertising, refer also to the
N515-T.
