I forgot to mention that Greifelt had similar style side frame reinforcement and the longarm in question is also similar to the Greifelt Model 96(Model 94 w/ horn triggerguard bow). Both E. Schmidt & Habermann and Greifelt offered a clamshell action DR and pretty much used the same term "Stabil" so I don't know which came first or if E. Schmidt & Habermann was sourcing Greifelt for frames. Greifelt did offer offer a hammer version of the "Stabil" DR as a Model 258. I don't know that Greifelt offered a Pigeon SxS with the barrel extensions as sideclips but E. Schmidt & Habermann did as their "Diamond" model.
August Schüler was the younger brother of Friedrich Schüler and I'm guessing their father or grandfather was also named August. August Schüler took the reins of the firm in 1850 and had 2 sons, Friedrich & Oskar, to come up thru the ranks. Prior to WWI, Oskar Schüler left the firm; therefore, leaving the business to Friedrich and his son Richard, who may have become a master about the same time. So Robert Schüler just may be the son of Oskar Schüler and it was Oskar that established the foundation for the business in Köln. Info suggest that the Friedrich/August/Friedrich/Richard Schüler had one whale of a machine shop and that other firms had access to their machinery. That may have been the case but more probable is that the shop of Friedrich/August/Friedrich/Richard Schüler was sourced by other makers, including Robert Schüler, for components. There is info that hints that Robert Schüler had a shop in Suhl but I would say he used that as a marketing tool but only sourced the Schüler shop in Suhl. Post 1915, or later, Richard Schüler thru Fredrik W. Hollender of NY supplied many of the last Charles Daly examples.
