1950s Zurich typewriter repair shop

Have a view inside the Baggenstos typewriter repair shop, Zurich, ca. 1953. August Baggenstos and his HERMAG distribution company was the general representative of Hermes typewriters for the German speaking part of Switzerland.

You see the mechanics at work at the Hermes models of the time. Can you identify them all?
