I know ive said it before but check the stan miles link in my sig. all the parts are campy from 1960-1980 except the bottom bracket and the stem/bar which is cinelli. Look for some nice older rims (mavic, fiamme, gipemme, campy) to really set off the wheelset

headset: lbs had one just sitting there. go figure.
admitedly, it took me about a year to get this bike where it is now. restoring a bike is a slow process if you have something very specific in mind.
