As for the '64 thing, only collectors care. Any lever before the cross bolt safety will be more desireable than after. The post '64's run quite well, nobody has done a 10,000 round evaluation to prove anything more than handfiled parts are simply overpriced. Entirely why Winchester started stamping some to stay in business.
No deer will ever tell the difference, whether covered in brass tacks or handled with a large lever.
Funny how pre '64 Winchesters are revered, but a well made Paki copy of the Enfield is crap. Obviously too much of a good thing? Handfitted parts requiring a gunsmith's exacting attention to get right really means poor fabrication and QC in production, requiring a lot of labor to correct.
In other words, collectors are willing to pay more for a company's production method that was pushing them to the brink of bankruptcy. Why that's considered "high quality" when it's blatantly poor initial workmanship will remain a mystery.
