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
