First off I am not sure if this is the right forum for this question. I am looking to purchase an early 90's Gueriotti frame off someone and it is made of columbus brain tubing and has the Varished by Dessena Carlos option. I looked all over for info on this frame and can't find any. There is no model name or number on the frame so I am kind of lost. Its bottom bracket is a cinelli if that is any kind of reference. My question is what would be a good price to offer him for it. It is in perfect shape almost new he never built it up. Any info or help would be apprecitated.
