Recently I found an old target rifle at a gun show. I couldn't identify it but the price was right so I bought it so I could research it and hopefully identify it. A friend who saw it sent me a link to an 1851 Feldstutzer article and it does look close. Rear sight appears to have been changed at some time in the past and the tang sight removed. Marked in a couple of places with G. Stahl. Can anyone shed some light on what I bought on a whim? Thanks
