my best was a 1981 carlton which I paid $75 for and got $375 and a Brooks pro select and old logo campione del mondo bars (i.e. I kept those items and tuned cleaned and flipped it with generic japanese replacement bars)... 531 frame it was.... That is easily that best often I don't make much money. I bought a late 70s marinoni for a friend and swapped a NR for the Rally RD and New logo stem and bars for the old logo cinelli stuff and sold it to him for what I paid... the parts I got were part of the agreement in my financing it for a month or so... But I put aero levers and new bar tape on it. But I have flipped so many I can't even remember... Bianchi MTB bought $45 sold $125... lots of stuff like that...
