Aside from a good watch, or maybe the piston and cylinder in a gasoline engine, what pre-WWII consumer good was machined to the same tight tolerances as a fine shotgun?

Where on earth did you get the idea doubles were built to some incredibly tight tolerances? Many are nicely built but there's nothing special about the fitting. I mean, even on the best guns the bores are finished near some pre-determined diameter, and are aligned to shoot in the same general direction. The well built gun is joined where most of the bearing surfaces fit, but not all. The stock is headed up well enough to avoid cracking, etc. Even the best guns are not perfect. They display excellent workmanship, not perfection.

I tend to agree with Joe. There is no way you can compare tolerances with a
Patek-Philippe for example.

Several yrs back there was a discussion on this forum about the fit of rotary bolts. When Alexander Brown came up with it he conceived it as a "Dual Purpose" bolt to both hold the bbls down to the action, & also to hold the standing breech "UP to" the bbl breeches. This was stated in his patent & some early statments he made concerning it. At the time a good number of members here did a "Smoke Test" on their rotary bolt guns; Smith's, NID's & Foxes & not a single one as I recall found the fit for that 2nd function, so in effect the rotary bolt offered no "Real" advantage over the simple wedge bolt of a Stevens.
Anyone ever check the fit of parts on an old Singer or Wheeler & Wilson sewing machine of this same era??

The generators in Hoover Dam first began producing electricity in 1936 and are still in operation today. Now that's a precision machine!!
