I would have to disagree with your statement to an extent. While it’s true that some sporters are too far gone, and the best hopes of “restoring them” end up with a partly matching k98k in military configuration….
The same does not apply to Late war sporters. For example, I have quite a few KM’s BNZ and Mauser Oberndorfs that are “restored” in original replacement stocks. The scrub walnut BNZ was a nightmare to find and took years but patience payed off. Bands are unnumbered as they should be on my examples and if I were to choose to not tell anyone, they would have a resale value just as other late KM examples which are supposed bringbacks without paperwork.
I also have a ce42 “sporter” that was sitting in a aftermarket stock but its owner had its original stock, bands and band spring. The only detraction to the package that its original handguard was lost so it has an armorer’s replacement now.
In my opinion, I would take a properly “restored sporter” over a RC any day of the week. At least a sporter in general retains way more of its original parts. Now of course if the barreled action is buffed and reblued, parts grinded down, etc… then it’s just a mil surplus hunting/shooting rifle.
