I've been the caretaker of two Lindner Dalys. The first picture is of an early one and although it appears to have an intercepting sear it does not. The bottom screws are actually the axle pins for the trigger sears, The top screws are really just to fill in the holes in the frame, at least that is my opinion. This gun is also missing the cocking indicators. The holes have been filled in and engraved and I believe this was done when the gun was made, however it could have been done at a later time I have no way to know for certain.
The second picture is of a later Lindner. In this photo you can plainly see the sear layout. BTW, this is the standard state of polish on these guns. All I did was remove 100 years of hardened oil with lacquer thinner for the parts to look like this.
