REMARKS:
=================================================================
The "-T"-Ext. in the model-number means "Traditional white".
This model is made of aluminum. It comes in a beautiful red-
brown leather case, with golden inscriptions » PICKETT « &
» CLEVELAND INSTITUTE OF ELECTRONICS « . It can be clipped
on the user's belt - typical for the USA: As seen in the
"Western Movies" ready for a "quick draw".
This slide rule is specialized to solve resonance-frequency
and -circuit problems: The H-Scale gives the LC-product for
a choosen frequency on D-Scale. The 2π-Scale is for inductive
and capacitive reactance problems.
The slide rule was part of a CIE course and the description
how to use this scales is to find in the course materials
