I've come into possession of a couple of old Regina Oro freewheels. One, almost unused, says "1 Italy 78" and the really used one says "3 Italy 80" . There is also a whole bag of, apparently unused, spare cogs that are are kind of a gold color. The largest cogs have are factory drilled full of 1/4" holes. None of the cogs have markings, not even number of teeth. I also have a bike and a ton of very small, new chrome parts marked "Campagnolo Brev" or "patent", but that's another question.
Can the list tell me something about these Italian parts that I know nothing about? Pictures available offlist.
