Boats,
For my two cents, I'd say those words apply overall, but with varying degree for each manufacturer. And I'm pretty much in agreement with Dave's observations.
Internally, the original Winchester and Remington rifles made for the civilian market gave you the same production standards from field grade through high grade. The internal parts weren't highly polished or jeweled like you find in the vintage American shotguns you've looked at, or like you see in a British-best double rifle, but they were very well made, heat-treated and fit, providing good servicability over an extended period of time.
Winchester's production to gauge with extremely close repeatable part tolerances resulted in minimal hand-fitting required. Remington's tolerances varied a bit more, requiring somewhat additional hand-fitting, but both manufacturer's gave you the same high quality regardless of grade.
When it comes to Stevens (and a number of other similiar primarily high-volume lower-budget manufacturers), you often see crude and rude internal fit and finish in the standard grades, changing to sometimes decent and better as you move to the higher end of their respective product lines. Part tolerance repeatability can be really sloppy, which required a large amount of hand-fitting, and you usually got what you paid for. To their credit, Stevens definitely improved their standards with the introduction of the 44 1/2, so maybe Harry Pope was able to teach them a thing or two during their brief association.
It's kind of a tongue-in-cheek joke that an original Stevens (44 1/2 excepted) is often as close as a standard production rifle can get to being a semi-custom one-off, before being customized.
