You'd be in a quandary what to do with that bike, if you were fortunate enough to acquire it. At one time, I'd strip the paint off and repaint it, but I now regret doing that a few times. I suppose we now have a better appreciation for patina. My own approach, FWIW, would be to restore it to mechanical perfection, while retaining the external appearance if it's not a complete rustbucket. But it isn't mine, sadly.
