My father has a rifle almost identical to that one. (different engraving). His was made in Suhl, Germany. I believe his is in 8.15x46mm, he has several firearms in that caliber. They often don't have makers names on them. Most all are made in Germany, but the Swiss, Austrians, Danish, Belgians, Czech's, alpine French & alpine Italians made them as well. You can usually identify where it was made based on the proof marks. Germany often had individual marks for different regions and towns.
I'm only able to recognize Suhl's markings, Belgian, some Austrian and most Swiss, with out researching it. Switzerland almost always has used a cross shape proof mark on its barrel. (same as Schmidt Rubin rifle, looks like plus + sign). Belgium uses an ELG inside a circle. Suhl Germany's for most of the time period was a angular crown over and N (for nitro).
They are now worth quite a bit and getting more recognition now. Their price growth has been held back because of lack of familiarity, not lack of quality. About everywhere its safe to say $1000 + in value. They can be sorta unpredictable when they sell.
