About this material

This is section C of the product catalogue 'Section A-C, 6th Edition Catalogue Telephone Instruments from Aktiebolaget L. M. Ericsson & Co, Stockholm '. The catalogue was printed 1911 by Wald. Zachrissons boktryckeri A.-B., Göteborg.

The scanning and word processing has been done by Tommy Sundgren (STSF).

Some pictures have Moiré interference that is hard to avoid due to the paper printing technique used. The text has been captured with Caere OmniPage OCR program.

Many thanks to the Telemuseum in Stockholm that kindly lent us the catalouge.
