Pickett 903 - Notes
|
|
|
|
- This is an old style Model 9xx series slide rule.
- 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.
- 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.
- 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.
