Sorry,gentlemen, but these are not intercepting or secondary sears! You are looking at Kerner's improved Anson & Deeley lockwork, adopted by nearly all other Suhl gunmakers after WW1. The original A&D sears, mounted in the lower receiver, have the sear notch very close to the fulcrum of the tumblers. So the cocked tumbler applies a lot of pressure to the sear engagement. This pressure requires a deep, solid engagement which in turn makes it difficult to get a light, consistent and safe trigger pull. So the British gunmakers sometimes employed secondary sears to prevent accidents.
The Suhl gunmaker Kerner found a remedy to this problem. He relocated the sears to the top of the action and linked them on a pin in the top of the body, as shown in the photos. The sear engagement notch is now located at the top rear of the tumbler, as far away from the fulcrum as possible. The improved leverage greatly reduces the pressure on the sear engagement, allowing for decent trigger pulls without compromising safety or durability. Secondary, intercepting or safety sears are deemed unnecessary with this arrangement.
