A Gift

A friend of mine who came over from Germany gave me this str8. It was his grandfathers. He figured it was bought sometime in the 1920's. Did some searching but couldnt find anything on it. On the tang it has O.Hoffgen Solingen and the other side has a 23. It's 4/8 wide it shaved really nice.
