After decades of collecting military Mauser rifles, I have finally purchased a factory sporter. Auction description says “ MAUSER TYPE A NO. 2 SPORTER, 7 X 57 CAL. BOLT ACTION RIFLE, RARE ENGLISH PROOFED FACTORY SPORTER, 1910 DATE, FACTORY ADJ. REAR SIGHTS, SERIAL #: 34874” and while I’m not sure it’s a type A, I believe it is a real factory sporter.

What photos would help confirm it’s generally correct?

Receiver has BU proofs. Bolt matches and has the same. Only down side is it was drilled and tapped long ago. Screw holes have filler screws now. Serial is as described and right for 1910 production.
