Nice looking machine...
Electrolux canisters of that era are tough to beat. Truly my favorite canisters. I don't have an Olympia One, but I have several others—1205 (2), Super J, Silverado Deluxe, Diamond J. That vinyl hose is a definite performance enhancer over the leaky woven ones. I have a relatively early 1205 that my dad picked up off a neighbor's trash pile when I was in high school. I was surprised to find it in their attic when they were packing up to move to a senior living community in 2016. I brought it home, stuck a vinyl hose I had onto it, and possibly for the first time in its existence, connected it up to a power nozzle, thus unleashing its true power. I had originally thought to keep it as a potential parts donor for my other 1205, but I ended up replacing the broken handle and adding it to the operational fleet.
