Emil Eckoldt, born 1854, died 1930, founded his business in 1876 at Judithstr.15, Suhl. By 1923 the shop was run by Hugo Eckoldt and Robert Schilling.
The British would call Eckoldt's action a "self-opening spring cocker". E. mounted hammers and mainspring on a see-saw like lever, hammers and lever rotating on the same pin. The front end of the lever protudes into the bottom of the action bar, where it is held down by the rear barrel lump in the closed gun. On opening the gun the front end of the lever is free to move up. An additional spring rotates lever, hammers and mainsprings to the rear, where the hammers are caught by to top-mounted, Kerner type sears. On closing the gun the barrel lump rotates the lever foreward/down, cocking the main springs.
