I'd like to see an image of the hammers, which remind me of the early Lancaster type. I'm curious if it was a British parts kit that Emil Eckoldt & Sauer completed. Nothing more than a wild guess, but Emil Eckoldt was a subcontractor to H.A. Lindner and performed some tube tasks so I'd say the large Es are his. He hung out his shingle in 1876, being 3 years after Sauer began to concentrate on sporting weapons. I'd date it to the early 1880s & possibly a little bit earlier. If you pull the locks, there may be some marks there.
Kind Regards,
