Extremely well done! I've done a few "Mauser Rescues" taking sporterized rifles back to "original" congifuration, but that is one sweet fix short of that.
My current K98 was a sporterized Russian Capture BNZ 45. It had the rear sight removed and the front os the stock chopped off much like the OP's rifle. I replaced the sight and re-stocked it with a late war laminated stock and a late war stamped front band. The rifle is pretty much as it should be for a 45, but I would be quite happy to have the OP's rifle in it's current configuration. While I'm always glad to see "original" K98, if a rifle has been sporterized it's great to see on like the OP's.
