To hijack this thread a bit farther, I ran across a SBT on what looks to be a Burkhard Behr type action with the phrase "Finished by L.C. Siner & Co." on the Behr like lockup. So it must have been peddled in Philadelphia from a concern that was an extension of John Krider. Maybe Dr. McPhail has additional info. Seems John Krider hung out his shingle in 1837 and expired in circa 1887 when a John T. Siner acquired the business. Circa 1903 a Leander C. Siner, probably a son, partnered with Charles Mohr to steer the concern, which seems to have faltered in the mid 1930s(1899-1931?). In the mid 1800s the John Krider concern looks to have mixed and matched with Joseph C. Grubb & Company, which along with the John Prey Lower thread hits at Grubb's influence. At some point info suggests that a Russian minister was attempting to place an order(s) with John Krider for folks back in Russian. Anyway, I think the SBT to have been sourced from Behr but I don't know if he had a DRGM/Gebrauchsmuster for a SBT or not. It seems to fall under DRP 154950 of 1904 and that would aide in dating as Leander C. was at the helm at that time. Interesting that Leander C. Siner notes that his concern only finished it. Seems he was truthful.
