Do the lugs have holes in them? If so it is generally thought that this feature started around 1968. If the equipment is in good condition (steel parts like bolts/hardware front dr cage etc are rust free and no badly scratched up alloy) and the frame is dent/damage free you may want to see if you can negotiate a bit. I assume the frame had chrome lugs and fork crown and if so what is the condition of the chrome? This adds to restoration costs if re-chroming is necessary. Check seatpost is 26.2 just to make sure it is a Cinelli and not a Windsor which takes a 27.2 post. If all checks out and you can negotiate a little you will have a great bike which will also turn out to be a good investment. Pics would be good if you can get them.
