Stuart, I was hoping you'd check the CR archives because there are many,
many posts covering all of your questions. Tullio had his QR and his
Cambio Corsa derailleur (note: the QR was his, the hub was Fratelli
Brivio's) made by FB. The very early ones were hand-made by Tullio.

There is a reproduction of the patent drawing and application in
Catalogo Campagnolo. "Kingdom of Italy -- Ministry of Corporations --
Office of Intellectual Property -- Industrial Patent No. 319062 (Applied
for 4 May 1933 - Released 28 June 1934) -- Tullio Campagnolo -- Vicenza
-- CHAIN-TENSIONING BOLT FOR BICYCLES." The patent drawing shows a
toothed dropout, long handled quick release and hub with two-sprocket
freewheel on each side of the hub.

Don't know.
> When did Campagnolo first appear on a hub rather than FB?
FB supplied hubs branded with "Campagnolo" along with many other bike
and parts manufacturer's names from at least the late-1940s (if not
earlier), clear up through the 1960s (even stamped SIMPLEX).
> Who made the early Campagnolo branded hubs?
FB (Fratelli Brivio - Italy). I'm reasonably sure that the first hub
that Campagnolo made in house was their all aluminum Record hub
beginning in 1958.

There were also EB (not a typo, "E") and Gnutti QR levers with "Lic.
Campagnolo" forged on them in the early 1950s or even before.

The intent of my Velo-Retro reprints of old catalogs (close to 100 currently) is to provide this information to people who are curious about learning more about the old bikes they find. The dates of the catalogs help in dating the bikes. There is a tremendous amount of date info in the CR archives and also many scans of old catalogs on Mark Bulgier's web site (there is a link on my web site links page). There is also a tremendous amount of date info on the internet that you can easily find with a good search engine like google.com that will also search out images and search the newsgroups.
