This is a beautiful 88-C long distance desk telephone made by California Electrical Works in a joint effort between the Western Electric Company and the Pacific Telephone Company, a Bell subsidiary in San Francisco (that's why it is commonly called "San Francisco" potbelly). Unlike most potbellies of its time, the base and shaft are made of a bronze alloy and cast as one piece. This also has a marked, high resistance White Solid Back seven-digit smooth edge transmitter and a marked American Bell outside terminal long pole receiver. Size 12" T.
