Australian Post Office
This instrument is the most well
known of all the smaller wooden telephones. It was basically a British
designed telephone and was supplied by a number of overseas manufacturers
including Peel Conner, British General Electric and British Ericsson. A
variety of local manufacturers also produced parts for the PMG (Sydney)
Workshops assembled instruments. Much of the timber used for the cases is
of local Australian variety and is the reason for the wide range and
variations in colour and grain found in these telephones.
Types 137AWH and 237AWH are of similar appearance but have over time included circuit modifications, improving overall performance.
Early variants were made by Ericsson (ref - 1914 PMG Circuit Book).
