Dan, you bring up some good points...the grade of guns and the finish relates to how much time was spent on the finish.
In my experience, all scraper mark disappear by the time I'm done rubbing the oil out. I don't fuss over the marks, they just disappear. This has a lot to do with finishing with a SHARP scraper, and not pressing down hard for the final scrape. When the wood is pressed hard, it compresses, only to swell back out again someday, no predicting when.
Scraper marks fade as the gun gets used, the wood gets polished, leaving a glossy/satiny finish. Another good point Dan makes is that most guns have been refinished, so who's to say what's original anymore?
The gun below is my copy of an original. I would call this a workmanlike gun, certainly not fancy, but one where the maker knew what he was doing. It was a tool, and finished up to do the job at hand. Yes, some minor tool marks are evident in areas where there is no wear, like under the cheekpiece, but overall, it's well finished. To me, this is a believable reproduction. But that is all subjective, and for each of us builders, we all have a different story that goes with our product.
There is no helping developing small facets when scraping. Maybe a thinner, more flexible scraper would eliminate the facets entirely, but they are not a problem to me, as the stock wears, everything softens and blends. i don't consider this to be a crude finishing method, but a practical one.
Certainly, on a high end gun, I'd put in more time to develop a blemish-free finish.
