There is a lot of older vacuum brewing equipment available out there with some looking.
I use a Nicro 1512 12 cup vacuum brewer which brews two USA quarts or 12 five ounce cups of coffee at a time. Nicro brewing equipment is normally available on ebay USA and is all stainless steel construction so is virtually indestructible. There is still a source for the gasket which fits between the lower and upper too. Nicro made a number of models with capacities of 8 to 12 American coffee cups or 40 to 60 ounces of water, 2 to 3 Imperial pints. The Nicro filter is a two disc all stainless steel labyrinth filter assembly which some consider to be one of the best vacuum coffee maker filters ever made so be sure one is included if buying a used Nicro brewer. They can work with other filters including glass rod filters and others. Some of the Hario and Yama filters will not fit due to the diameter of the recessed area the filter sits in within the upper pot assembly. All Nicro and large gasket Cory and Silex upper units have a similar size and shape recessed area the filter sits in and the gasket seats over and grips.
Other all metal vacuum coffee brewers were made such as the ABCO aluminum ones and some under the Cory name but they are scarce compared to Nicro units.
Glass vacuum brewers were made by Silex and Cory as the primary makers. Gaskets are still available for Silex units, both large and small neck versions, and large neck Cory units. Silex made units in 4 to 12 cup sizes and Cory did 6 to 12 cup versions that I know of. Both are Pyrex borosilicate glass construction so are breakable. Readily available on ebay USA and frequently cheaper than the equivalent new model plus available in larger sizes that no one makes today.
Other American vacuum brewers from the 1930's through 1960s era include Sunbeam automatic vacuum pots in metal construction and gaskets are still available for them. More to go wrong with a fully automatic unit IMO. As I live at a high enough altitude I want manual control to try to compensate for lower brewing temperatures. Automatic brewers also are usually power specific and an American 115V 60 cycle unit may not like 220V and 50 cycles.
The big killer for use of many of the old American vacuum brewers is gaskets as it is now 50+ years since they were made and the gaskets do dry out, harden and fail. For other than the mentioned units, which still have gaskets being made, getting a good gasket may be difficult to impossible and the units are shelf queens without a good gasket.
Cona vacuum brewing equipment has been made for a long time and still is so is widely available used too. Current new items are overpriced in my opinion and I personally prefer stove top vacuum brewers so find spirit lamp and butane burner coffee makers a bit ridiculous and obsolete.
