Fella:
Below is some text on the Kerner - Anson(Deeley Body Action) platform w/ 1/2 pipe side-frame reinforcement. When you view the back of the frame it is the pin/screw configuration that gives it away. You should be able to search this site w/ the term Kerner & find all the info you desire. To point to a specific Suhl mechanic, you'll have to go over the example w/ a fine toothed comb/glass & look for initials & related touchmarks. These may be under the rib, back of the action under the stock, etc.
"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."
"Below are a few DRGMs issued to the Kerners:

******"Gebrauchsmuster - DRGM - 531992 - Vom Schlossblech unabhängiges Nachspannschloss. Ernst Kerner, Suhl - Me thinks this just might be the culprit????*******"
http://www.doublegunshop.com/forums/ubbt...true#Post495354Until then, it was made in Suhl by a subcontractor-mechanic to Robert Schüler.
