I have a JP Sauer mauser 98 Sporting Rifle from the 1930s.
On the right side of the receiver ring is a stamped serial number, and this same number is on the bottom of the Octagon/round Krupp barrel.
But there is also a different serial number on the bottom of the receiver behind the recoil lug. This second number or at least the last few digits of it are also found on the Bolt, shroud, safety and cocking piece. As would a numbers-matching military rifle.
What is odd is the location of that second serial number. Being on the bottom of the action. As most military action serial numbers are on the side of the receiver, at least visible with the stock on it.
I wonder, is the action maybe one originally built for Military use and then built into a sporter by Sauer. Or was the action maybe sold to Sauer by Oberndorf as a sporting action meant to be assembled by Sauer in their own way. But I thought Sauer was making their own actions as well.
Either way, the action had one number and then the second number was put on it when the rifle was finished.
