Photos, please! Especially of all the proofmarks. Eugen Scheinert was a country gunsmith at Herrenteichstr. 23, Osnabrück. Shop taken over from j.Dahl in 1880. Scheinert certainly is just the retailer, as usual. He certainly had the gun made by the specialist makers in Suhl. The WK on the barrels points to the well known Suhl barrelmaker Wilhelm Kelber. The Wk on breechface is the real maker of the gun, but here the shape and arrangement of the letters is important for identification.
