Let's assume it experience proof pre-1910. You have one of the best mechanic's effort on the tubeset as well as the most expensive tube steels that was offered. Sounds like a quality to me.
Here's some lifted/translated info:
Waffenhndler Wilhelm Knig, Liegnitz
In 1905, the Burgstrasse 62 on the ground floor is the E.B. Knig, Wilhelm, Bchsenmacher, Waffen = und Munitionslager. In 1914, the street is Burgstrasse 62 E.B. Knig as Buchsenmachermstr. In 1921, at 1 (same address) B. Knig and E. Knig. In 1930, the owner of the building is Wilhelm Knig, Rentner and under no one there A. Knig. In 1939, there Bes. Konig'sche Erb. Eu 1 Knig Marg. , Buchsenmacherei. When it comes to Bartsch, in 1878 he is listed at the same address (Adolph Bartsch, Burgstrasse 62) as Gewehrfabrikant. It seems that Knig took over the business after Bartsch.
