[Description] A PATENT-78 Nuovo Record derailleur with the moderne MASI name down the front of the derailleur body, and italian colors on the upper shoulder and around the lower pulley outer plate.
It's the only pantograph rear derailleur I've ever seen !! generally, pantographing was applied to wide expanses of flat aluminum, and a nuovo record derailleur really has NO flat aluminum to start, so it must have been a real PITA to make !!
