A brown, TSR1004, the Ericofon 700 was the third case design for this iconic telephone, released in 1976 to mark Ericsson's centenary and designed by Carl-Arne Breger. Easily distinguished by its square design, changes to the handle and the addition of a push button keypad instead of the rotary dial in the base, it was never as popular as the earlier models (see AIBDC : 008464 and AIBDC : 005804). Only 41,000 copies were manufactured at the Karlskrona factory in Sweden until 1984. Available in the UK in brown, green or white with a black base, this example was made for the Post Office's 'Special Range' of designer telephones and was injection moulded. It has a round plug No. 505 attached to the cord which prevented the user from removing the telephone from the line.
