sometimes new possibility's just around the corner, find a gentleman living just 20 km from me. because he is a paper collector only our way's dont meet before but now its just in time.
he send me some prussian paper's and the first thing I see were two patent's for Nicolaus von Dreyse (the second ) given to him on the 3rd of july 1896

-61730 hammerless self cocking Drilling with three trigger's

-61731 hammerless self cocking doublegun

I had two Drilling's here, one clearly N.v.Dreyse, with 3 trigger

and no doubt this is the unknown double gun

N.v.Dreyse SN 36620 so made in 1896

another model is identified, probabyl only made between 1896 and 1900 it must be rare

and the gentleman have a book project about the Teschner - Collath gunmaker family nearly finished too
