Hello Chuck,

Those models sound correct for that timeframe. I've seen both models
on ebay recently. There are lots of people with whom you can deal
directly. The best place to look, in my humble opinion, is to start
with The Oughtred Society home page (www.oughtred.org). From there,
you can find just about anything and everything to may want to know
about slide rules. Contact me again if you have any more questions.
I can point you in the right direction, in most cases. Take care.

Sincerely,
Amin
