Very nice engraving on a very plain rifle. Looks like the work of a German engraver simply because of the prolific use of the oak leaves. An English or Italian engraver would include some kind of beast which, is also common with German engravers, but just oak leaves, I'd bet German. I feel that if it was a presentation gun, they'd use a rifle with top quality furniture. Hope you can get a definitive answer, very nice rifle.
