Buckstix-
The photo below is the one you requested, but I'm a bit late because you posted a part of it above. You're also better at avoiding edge effects with a scanner.

The caption states yours is a "three-slot 458 Mauser". I'll admit unfamiliarity with the 3-slot term. If it's not a typo, would you clarify?

Page 193 shows a stock inletted and with with glass bedding for a "big-bore Mauser". There appears to be a serial number in the glass bedding of the recoil lug. Does that match your rifle?
