Need help looking for any information on this manual cord switchboard
This switchboard was given to the Edson and District Historical Society (EDHS) as a part of an Alberta Government Telephones (AGT) collection. Accessioned in 1986, it sits in the Edson Galloway Station Museum.
What do we know so far? It was made by Northern Electric (separated from Western Electric in 1949). Only model number found so far is from the vintage Western Electric calculagraph KS7769L-11 No.33 20V version. Late 30s-60s model. Possibly 3 PBX units put together with the last date used being around June 1977.
What are we looking for? The model number and when it was used are the main goals but every bit of information will be taken.
