Below is Axel E.'s opinion on the platform:

"This is Emil Kerner's improvement on the Anson and Deeley boxlock. By relocating the sear detents from the bottom of the hammers to the rear tops, as far away from the fulcrum as possible, Kerner greatly reduced the pressure the detents have to hold. The improved leverage makes secondary intercepting sears unnecessary. Simson/BSW incorporated Kerner's top-hinged sears into their boxlocks in the 1930s. Since then these sears became the Suhl industry standard. All post-WW2 Simson and Merkel boxlocks feature Kerner's sears. Barthold's "Jagdwaffenkunde", the GDR time textbook for gunmaker apprentices, show no other boxlock design."

It was adopted as the staple and workhorse in Suhl and was prolific even until today?
