Interesting to see that Wittener Stahlrhren-Werke was founded in 1896 by absorbing or as a reorganization of Rhrenfabrik von Alvermann, Cordes & Trottmann. The owner was von Khaynach of Stting. Telegraph address was Rhrenwerk, Witten. In 1905 it mergered with the Rhrenwalzwerke in Gelsenkirchen. An expansion in 1911 lead to a satellite facility in Glasgow that was supposed to be online in 1914 followed by a merger with the Mannesmannrhren-Werke, which commenced in 1917 to fully absorb the concern and the deal was finalized in 1918. Info is spotty after WWI under the Mannesmann umbrella.

Ken:
What is the earliest Charles Daly/H.A. Lindner example wearing Wittener Excelsior steel? For now I would guess the trademark was filed between 1896 & 1901 but much closer to 1896.

Kind Regards,
