I'd really like to see the marks. Can you take a large diameter magnifier & snap an image thru that in white light? Nah, not really Birmingham sourced as one unit unless it wears a contingent of Birmingham marks. I'd say the tubes were knitted and that component along with the frame was/were in a very blocky rudimentary state. The bulk of fine fitting, profiling, polishing and detail work was performed by a small talented pool of Suhl mechanics with which Charles Daly had a loose association. It wasn't until the mid 1870s that Charles Daly truly defined his primary sourcing, which was thru H.A. Lindner. I suspect that during the early years in the interim period that not only was H.A. Lindner learning his craft, but in Lindner Charles Daly was cultivating exactly the aesthetics required for the American market. It was a pairing that just would not have succeeded without all the principal players. And S,D&G benefited greatly in the monetary realm.
Kind Regards,
