Hi, I confess that most of my info on German Schutzen rifles comes straight form Volume 1 & 2 of Alte Scheibenwaffen. I bought the books to research my own 8.15 x 46R rifle which turned out to be a very late production Buchel Meister with few obvious markings.
My Swiss Federal Muzzleloading Rifle is equally confusing. it has all the original finish but the sights were gone when I bought it. I mailed somebody on the Swiss Muzzleloaders web site to enquire about the avalability of original sights---I was told that they are available because the Swiss take them off and fit Pedersoli globe and aperture sights--I did the same. The only markings are a small coat of arms in a shield and the number 15. The barrel is one turn in 32 and heavily choked--it will not shoot a patched ball well. I use a .41 dia grooved wadcutter, dip lubed and loaded over 38grs of Swiss 3fg for the 50m comps.
