I own Charles Daly hammerless serial #7 ("Lucky #7") and its APUN is 65. With 11 serial numbers between Dalys #7 and #19, it is obvious, looking at the 59 number APUN delta between these two, that other makers besides the maker of these guns were taking advantage of the new and excellent A&D design - as you would expect.
Ken:
Do you think these makers to be solely Belgian, or a mix of Belgian, French & H.A. Lindner. I'm pretty confident that the A&D breechloader design protection was sought in France, but I am not sure about Belgium and I do not think it was filed in Germany.
Maybe they filed in the Countries where there would be the most competition and where international law might apply. Have no idea on the international law for the period.
Kind Regards,
Raimey
