BRUNSVIGA - Gehirn von Stahl. Display cabinet 1 in Room 3

BRUNSVIGA wall clock with explosion timer.

The explosion timers that remained in large numbers from the war production were made into wall clocks with a pendulum and weight drive. These clocks, with bodies out of wood, pressed wood or baked clay were built between 1945 and 1948. The design for the body of the clock originated at the “Arbeitsgemeinschaft für Werkstoff-Formung” (“Working society for raw material shaping”) The mechanism was a slightly modified explosion timer for an 8,8 cm flak grenade. The clock on display is a gift of the former Brunsviga-employee Heinrich-Wilhelm Böhme.
