Most of the brewers at your history site are the "ancient and primitive" kind, but of course the site's intent is to show all the variations.

So far as I recall, none of the later (Pyrex) domestic use pots had any ground glass joints or fittings. The vacuum pot didn't get popular for home use until the big rubber gasket between the pots came into use and was reliable enough for home use. The common ones I recall looked most like the 1938 Silex shown at the site. Silex did market in my area, but the essentially identical Cory was far more common for home use.

Brewers of this kind are available at local hardware stores now, and they do still work, although the "automatic" electric things have pretty much taken over the consumer market. Commercial places all pretty much have the Bunn automatics: punch a button and something brown comes out - marginally drinkable unless you've deadened the buds with a recent Starbucks - which makes anything else taste good.

When I say 7 cups a day, I mean seven fourteen ounce mugs. But that's just an average.

Good coffee brewers are easily available, unless your standards run to the exotic; but a decent coffee mug is unobtainable in my area. My favorite is more than 55 years old, and irreplaceable.
