George:
TriStar is a brand that has been around in one form or another since 1940.
It was originally called Compact, invented by the Interstate Engineering Company of Anaheim, California, which was primarily a manufacturer of aircraft components. IEC needed to be able to clean up the interiors of airplanes after they had finished installing their components on them, and so they came up with a lightweight (for that era) and small vacuum made of the same magnesium-aluminum alloy used for their primary products.
Eventually, someone at IEC got the bright idea to sell the cleaner to the public, as a way of diversifying the product line, so as to help IEC weather the ups and downs of the aircraft business. The cleaner was dubbed the "Compact," and sold under that brand name for many years. Compacts were always sold door-to-door, but there was a retail version - identical except for the brand name - called Revelation, sold in stores.
Eventually, IEC sold off the Compact line to a company called Figgie International, which in turn sold it to the same Texas holding company which now owns Aerus. The machine was re-named TriStar.
The original Compact design, with detail changes and the addition of a power nozzle, was sold through about 1998. The company then introduced a new design, based on the old one, but more modern-looking and cheaper to produce, called the MG Series.
The later Compact-based machines made in the last dozen or so years before the MG Series was launched are very desirable vacuums, with metal bodies, as well as metal wand and tool systems (except for upholstery nozzles, dust brushes and crevice tools). They have a quadruple filtration system: Air first passes through a cloth dust bag, then a paper one that fits inside the cloth bag. Next comes a motor pre-filter, and last comes an exhaust air filter.
Below is a picture of my restored TriStar CXL, which is complete with everything it had originally, plus extra wands. It is my opinion that no finer classic canister vacuum has ever been made. You would enjoy having one immensely!
P.S.: If you ever look at a TriStar CXL, check out the suction - you will not believe it.
