CB-35 telephone

The CB-35 is a central battery telephone manufactured by the PZT from 1935 until the first years after World War II. It was the first Polish telephone with a Bakelite handset and a centrally located cradle button activated by picking up the receiver. Its housing is made of painted steel, and the PZT emblem is punched into the dial. The telephone represents the design language typical for telephones of the 1930s.
