Looks like some one sporterized a 93 mauser.
If you get a better picture of the crest I can tell you more as well as any other marks that look like arrows or crests. To make it stand out better in the picture pit some white out on the stamps and wipe your finger over the marks. The white out will fill in the mark and comes out easily.
What I have looked up in the Mauser Book It looks like it is a Oviedo Spanish Rifle that has been cut down and the safety has been replaces with one that will work with a scope.
Good shooter.
What are you going to do with it?
Mount as scope and use it for Deer and plinking or are you going to try to find all the stuff to make it back to Military specs? If so great project, but holly cow will it be expensive.
