Very nice find. I found this bike near the Citty of Tolmezo. Ex owner told me that was his uncle's bike. When I saw it I immediately understood that it was very well kept during this 40 years. It seems that it was storaged in the house and stayed there in dry and dark space. The bike is like new. It has some chips on the top tube and on the tube oblique because of the bike stand. The group is like new. The crankset is Campagnolo SR non fluted with 3 chainrings. With the bike there was another pair of new Rims with another sprocket and beautiful pair of F.Moser bags. The owner has a new pair of gloves F.Moser but he want to keep them. All hubs are Shimano Dura Ace. Surprise is another 3ttt handlebar with another Pantographed stem and Modolo flesh levers for citty use.
I searched for brothers Ravazzolo and I found that they were from Padova. I didn't find a lot about them, but someone told me that he remembered that brothers Ravazzolo made frames for other big names. Because I saw a lot of similarity on it with F.Moser frames I supposed that maybe they made frames for F.Moser.
I found Moser collection blog where it says what I presumed about building frames for F.Moser.
The bike is preserved.
