Parts for Keuffel and Esser Slide Rules |
KEEP ISRM FREE! Donations are tax deductable |
Model Numbers: Keuffel & Esser slide rule model numbers often have alphabetic
prefixes and suffixes. For example "N4081-3" indicates
a "new" revsionof already existing model 4081-3. These
revisions usually amounted to nothing more than a re-arrangement
of the scales; the physical sizesof models with and without the
"N" are absolutely identical. Any case or cursor
that fits a model without the "N" will also fit the model with the
"N." The "N" was usually dropped after couple of years when
people had gotten used to the new scale arrangement.
