Nathan,
Please accept these humble apoligies. I guess we all get a little skeptical when we see a bike like your Colnago listed on Ebay. Your bike isn't the first to receive such scrutiny and probably won't be the last. Some of us aren't as knowledgeable as others and asking those questions and pointing out specific items helps all of us learn from the ones knowledgeable enough to answer them.
