Thanks for the effort reb87. The horn pistol grip, the metal buttplate, the pinned forend and a few other characteristics upon first glance make it seem to be from the mid to late 1870s when the 9.3X72R arrived upon the scene. But it does have post 1893 marks. Considering the marks on the scattergun tube being along the side and not on the flats and the aforementioned characteristics, the longarm may have been proofed at a later date after its manufacture or it was made when it was proofed of on-hand, older, components. Is there a mark beside the "35" of the "118/35" plug gauge diameter stamp?

Although implied, I forgot to note that Sauer probably was sourced by many of the Hofbuchsenmachers, a title sometimes acquired by payment or political appointment, and M&G advertisments do exist tauting a Sauer patent.

Kind Regards,
