My '70 Paramount P13 came with its original Nuovo drivetrain - the RD is an undated variant reading only "PATENT." It's anywhere from '68-69. Original hubs were long gone. Serial E7009.
The '72 P13 has a '70 NR RD on it...and curiously enough, a January 1973 small-rivet Professional on it. I'm not entirely convinced the saddle is original though - the frame is C72158.
The '61 P12 only has its original front hub to date it by (no date on the Campag Gran Sport RD, obviously) - hub is from 1960.
