Hinged and sloping yes. 23301 iirc but no Mauser specific stamps or proofs. Found host. No where on this action is there any evidence of adaptation. It is a very slick and well designed rig. The trigger is awesome. Notice how the guard screws are so offset compared to normal. No rust in the action just crud. Stock isn't even saturated. Sorry that there are no full length pics at present.
