A wonderful 1950s two-tone Bakelite rotary telephone, model W49 made by Hagenuk, developed in 1949 for the German Federal post office. It’s special feature is it can converted from a desk phone to become wall-mounted by adjusting the fork and number switch housing by 180 degrees. You can immediately start making calls by simply plugging it into your phone socket! See it ringing here: https://www.instagram.com/p/CMSa9h7nY-t/?igshid=codn8phg979o
