Just a point as well as I am not a Mauser expert, it maybe all matching just all matching for a post war nation (such as East Germany, etc.) where they may have refurbished it with a late war stock/post war stock. It most definitely isn't factory matching though, which is a very rare state to find. Sorry I can't be much more assistance, I tend to avoid things like K98ks as there is so much to know and so much to fake.
