I just got this 1871 Jägerbüchse here recently. It is definitely seen better days. The manufacturer mark is there but it's extremely light mostly damaged from all the rust and pitting. Here is the rifles information with three photos.
1875-1876/ÖWG/7052E/E.4.119.
Mike, I added the rifle to the trends page with post #; does it have the Cypher?
