RE: SCIATHACTOR

[Cordasco, Anthony (NJ Data Services)]

Forgive me if I am repeating something which was already posted.  I am new
to this list and would like to know if anyone has any information on
something I have called a "SCIATHACTOR".  It has printed on the page 'the
author's dialling square based on the Middleton scales'.    It is a triangle
with latitude markings on two sides and hours on the third.
