I recently picked up this J.P. Sauer "Oberndorf Mauser". I was looking for a classic styled rifle but I don't know much about them. I was hoping someone could give me some information on it. According to articles by Jeff Stephens in the fall and winter 2004 issues of Double Gun Journal #206010 would have been made around 1912. Does anyone know if Jeff is still collecting serial and mauser numbers to establish Sauer manufacture dates? It is an 8x57 with the .318 bore, swaging and reloading dies came with it. It has the half octagon/half round barrel and a full rib. I was surprised at how light it is, 7 lbs even with the thin leather sling. Is that the usual weight for this type of rifle? It has been drilled and tapped for scope mounting and from the pictures on this site it looks like the bolt handle has been replaced. Other than that it looks original to me. Most of the rifles like this I have seen on the internet have set triggers, but this has a two stage trigger. I plan to have it reblued, would the proper type be rust or hot blue. Are there other pictures of the rifle that would help? Thank you for any comments, good or bad.
