It is a great thing, both the rifle and that you can keep it as manufactured! There are some nice collections in France, or so it seems with the rifles other forums sometimes show. MauserBill, I believe, pointed me to such a French forum and they had quite a few excellent rifles...
1913 is a tough year to find too, only Spandau, Mauser and Amberg are known to have made G98's that year, Spandau easiest to find, with Mauser and Amberg about equal. The numbers known and by serial extension suggest they made about the same number of rifles in 1913.
Yours is a very nice rifle.
