How to Use Pickett 400 Business Slide Rules
This manual came with a Pickett 400 slide rule and is
in fairly good shape after being folded for 40+ years. The manual has instructions for a range of basic functions as well
as for the specialist markup and business ratios. This manual is the same as another version I have except it is in a smaller
format with a paper cover whereas the other is larger and has a cardboard cover, refer to this
Pickett 400 manual.
