Telephone with small round plug, so-called Wincrantz model, LM Ericsson (Ericssons), Sweden, 1929
In 1929 Ericsson released this model based on the exclusive new art deco style, developed from the 1925 Paris International Exhibition of Modern Decorative and Industrial Arts. This new model was refined in both form and surface material compared to the 1909 metal model. The smaller format required smaller parts inside as well. The chromed, slightly elongated and graceful receiver gives a classy, metropolitan feel. Ericssson director Karl Fredric Wincrantz is associated with this model, which goes by the abbreviation "Wz". This telephone was manufactured in relatively small numbers, but was used in disproportionately many advertisements to elevate the company's image. Telephones for use with the new automatic exchange had previously had the dial added after the fact; this model was designed for the new era. Its manufacture ceased when the new plastic, Bakelite, began being used in telephones in the early 1930s.
