I hear you on the it's only original once , also if it's a significant bike with a past then maybe don't even touch it put in a museum . I have done a few resto's , I call them builds because I don't use stock components they are close but mostly not correct . They start out as a bear frame not even a fork and then I wind up with 3X's in it than what the bike is worth . But I don't care , none of my bikes are grail . Right now I'm doing a freshen up , the frame came to me as frame / fork / headset . I'm not going to paint it (although it needs it ) and of course I'll have 3X's in it than what It's worth . I'm on a roll (pun intended) .
