Reviving this old thread since my search for Marchesini found it.
Long story short, I was looking for bits for my circa '80s Masi and found this circa '75 Marchesini that was in my near area, so was able to purchase and avoid shipping. Its probably a tragedy to remove all the parts for my Masi but the Marchesini at 56cm is slightly too small, I like 58..62, and my Masi is a 60cm. The good news is that I will be making the Marchesini frame available to someone more fitting. Here is the story from seller and the components:

Super rare vintage Marchesini road bike. Marchesini was a frame builder from Bologna that made high end road bikes.

Purchased the frame from American Cyclerly in San Francisco a few years ago intending to ride it in Eroica events. Everything on the bike is 70's period correct. Specifically I built the bike up with the following components:

- Campy Super Record drillium brake levers
- Super record crankset
- Super record derailleurs
- Nuovo record brakes
- Super record seat post
- Nisi wheels (with campy hubs)
- Beautiful vintage Brooks professional saddle (patina).
- Cinelli 70's era stem
- Cinelli Campione Del Mondo handlebars
- VIntage Campy Record pedals

Bike has brand new Vittoria Rally tires and Selle Italia leather bar tape.
