Eric,
I don't think the Campy water bottles would be "on topic", but they would definitely be period correct for the Croce D' Aune group. I have six of them that I purchased on the same order with that group when it first came out. As for looks, I think it depends on the paint scheme of the bike. They look fine on a bike with an 80's paint scheme and graphics, even okay on my early 80s DeRosa with Super Record, but out of place on my early Colnago with a Record group. They look even better and seem to fit in with the Victory group. Two mounted on a bike with the Victory group looks kinda art deco-ish. In actual use, I didn't care for them and used them mainly for display. Just my opinion.
