Too, I forgot to note the long toplever. I have not idea on the serial number without seeing it. H.A. Lindner was about the only one in Suhl paying the APUN, and Charles Daly was behind that because of the end users in the U.S. of A. Now I do not know if H.A. was getting raw blocks of steel from Liège with the APUN stamped on them and then H.A. Lindner had a subcontractor to file it? Or if the frame was already filed in Liège w/ the APUN and H.A. Lindner polished and added the components? And Sauer was about the only other Suhl maker to offer the A&D Body Action with Belts & Braces, but after the APUN protection period ended.
It would have been nice to see if Lindner's 2nd series Quality Control Stamp was on the tubes. Being so early and completed by early 1893, I would hazard a guess a Lindner number, but that is just rampant speculation.
