FP, You have what I think maybe a good discussion regarding the "regular" SS "Kulturzeichen" on the Type 1, 2 & X chain links. However I believe what we are discussing is the conditions of manufacture and placement of silver "Hallmarks" on .800 and above silver pieces.

Here is an example of a .800 "Siver" SS Chained Honor dagger. Image taken from:
German Daggers of WW2 by Thomas Johnson. pg. 419. Note stamped .800 silver hallmark on link.
