years ago I bought an original mauser in 10,75x68

when the rifle came I was trying to load a round into the chamber but it did not close. common 8 mm brass fit under the claw but the bigger 10,75 case dont go. then I checked the rifle and found out that everything had matching numbers except of the bolt. send the dealer an e-mail if one of his rifles had a bolt matching my serial number and thanks god it was there.
