$800 for that parts is a good deal. It's not just a nuovo record group, It's a complete period correct pre-CPSC nuovo record group with all the goodie like cinelli stem and bar (a minimum $100 value) and rims and tires and chain and cassette... etc...
A good buy no matter how you look at it.

Uh oh... the FD isn't period correct! It's a pre-1973!
