Pickett 903 - Notes

  1. This is an old style Model 9xx series slide rule.
  2. This rule seems to be a progression of the 901 series which does not have the T and S scales and the 902 series which does have these scales but does not have the CI scale.
  3. Later versions of this rule have conversion scales on the reverse whereas this version has equivalent tables. Refer to this example of the Pickett N903-T.
  4. The cursor on this rule is only one sided and appears to fit in the outside channels of the rule, on close examination it does not appear that a second face was ever installed on the rule.
