Yes, those are the same descriptions in the 1870/1871 Schoverling & Daly advert. The 3 pin configuration is the breaking point from lower run to upper rung. The following image of the Golcher with U.S. of A. Patent #95998:


is the same as image in the hammergun in the 1871 Schoverling & Daly advert.

And here's what I guess: Daly was sourcing components or parts kits from W&C Scott of Birmingham until late 1870 or 1871 when he established his "factory" in Suhl, which was just having Georg Lindner to subcontract the work using components sourced from W&C Scott. Prior to that he may have been having the work performed by American craftsmen like Golcher & Overbaugh but the marks on those pre-1870/1871, or lack thereof, may answer the question of effort sourcing. Or, he may have been having William & Charles Scott manufacture his wares. Joe Wood may have a Daly Gun that is the missing link.

Mr. Hallquist's Daly gun is an early one and probably pre-1874, or when H.A. Lindner commenced applying his quality control mark.





Possibly Albert Stobbe(founded 1865) if "A.S."





Possibly a forerunning to the Lindner-Daly wide forend hanger.

Then there's the George Golcher & other Golchers in the mix:
