hey guys, i'm going to look at a late 70s to mid 80s Guerciotti in a couple days and wanted to ask for some sage advice. the guy who is selling says its has all original components in working order(campy/suntour), serial number 137279, decals are stripped, has some paint fade and chips(its dark red and silver/alum) but no dents or dings, normal wear and tear, needs cleaning and polishing...i was going to take a bunch of pics, but is there anything i should be focusing on when i go check it out.. how much is it worth?
thanks so much for any input
