New bikes have a "cassette" system, where the freewheeling mechanism is built into the hub (called a freehub), and the cassette is just cogs, which slot onto splines on the hub and are held with a lockring. In older bikes, pretty much up to the early 90's, the freewheeling mechanism is in the cogs, hence it's called a "freewheel", and it screws onto the hub. There was an inbetween sort of thing made by Maillard called Helicomatic, where a freewheel was held on by helical splines, sort of part way between straight splines and threads, but it didn't work well, and parts are hard to get now. I would get rid of anything Helicomatic, but if you had such a thing, and decided to keep it, I'm sure you'd find lots of people here who had retired theirs, and would be happy to sell you hubs, freewheels and parts.

My pleasure. If it's a freewheel, then getting a replacement freewheel, hub, or anything else is not going to be a problem for you.
