Just some notes in passing, the bullet weight used for the proof effort was a Copper Jacketed bullet of about 278 grains. And it wears some antiquated strikers.
The measurement of the length of the water-table confirms my suspicions that it is indeed a longer version. Most German SxSs had a length of 48 cm whilst H.A. Lindner-Charles Daly had a length of 56 mm and his sidelocks @ 62mm. So in comparison that's 2.2" for Lindner's wares to 2.1" for the subject longarm. Too it has what looks to be the Treble >>Bump<< on the forend-iron. H.A. Lindner married into the Triebel Klan by marrying Hedwig Triebel on April 27th of 1877. Now I am not saying it was sourced from Lindner by any means but the Triebel forends have that bump & longer water-table frames lie w/ H.A. Lindner, whose son Ernst Lindner(06.07.1883-16.06.1915) fell in fierce fighting w/ the Brits in mid 1915 leaving widow Gertrud Schorr Lindner to occupy the premises till 1948. Maybe post 1915 H.A. Lindner had a Garage Sale of Gestecks & some enterprising mechanic picked up an Old Lindner Hammergun Gesteck for a song & cobbled together a DR. Remember too that R.S./Robert Schlegelmilch was the prime tubeset knitter for H.A. Lindner. Just rampant & wild speculation but then again there's a lot of hammenstance with the Hahn Doppelbüchse??? Considering the above, that too would narrow the date to 1916-1923 and with the bullet weight & type on the side of the tube, I would narrow the date to 1916-1919.
