I am restoring an old Legnano Gran Primo and I need help on determine the exact year of production. According to the owner, the bike was sent back to factory for repaint in 1972 so the stickers are authentic but not original. The component are all campy super/nuovo record. The bike is packed with dry oil and dirt after 30+ year in storage. It also rusty but I clean it up nicely. I will post more picture as the build progress.
