Given the proofs I saw, if that is all there is, it pre-dates the 1891 Austrian proof law. With that and the style of hammer and other features I believe it is 1880's. The Austrian state of Carinthia had a voluntary proof law from 1882...and I haven't quite figured out how a law can be voluntary but that's what the book says. Anyway, those marks are not evident on the rifle.
At any rate when the rifle arrives and I acquire brass we'll see how close the sights are to original type BP loads.
