Bell Labs Technical Journal on F1 Handset
« on: June 16, 2011, 02:07:35 PM »
I have a digital copy of Vol. 18, Issue 3, July 1939, article: "Plastic Materials in Telephone Use" - of the Bell Labs Technical Journal. It covers items of interest such as fillers and "layers" which have been subjects of Forum postings. Send me an email at: cihensley@aol.com  if you want a copy.
