Mauser 6.5 mm Oberndorf

[Marshman]

I have a Mauser 6.5 mm 24 inch barrel Sporting bolt action rifle. Stamped Waffenfabrik Mauser - Oberndorf with Serial Number 96012. Two Triggers. 6.5 N stamped on barrel with PORT. stamped directly above. British Proof Marks (purchased in Kenya early 1950's).
Does any body know Year of Manufacture & cartridge dimensions for this rifle?

Your Oberndorf was manufactured between 1926 and 1927. You have the pre-1922 stamp. The Oberndorf stamp changed in 1922, but it was not unknown for post-1922 rifles to have the pre-1922 stamp.

Throw a couple photos up and lets have a look at it.
