John Barron's guide to Gran Sport differences

1965 - 1973:  Record
 chrome over
bronze, improved range and performance over the earlier Gran Sport.

1967:  Nuovo Record
Aluminum alloy rear derailleur was perhaps the "standard
of high performance" longer than any any other derailleur.

1967: Valentino
economy derailleur

Gran Sport front derailleur is similar to Valentino front derailleur

Telling the difference between
the Gran Sport front
(top of the line in 1950s) and the Valentino front derailleur (economy model of the 60s & early 70s.)

1971: Gran Turismo
 was a super wide range
but inexpensively made unit

1973: 1st generation Super Record
 It essentially
was a Nuovo Record unit with titanium top & bottom pivot
bolts and black anodized upper & lower body parts.

1974: Nuovo Gran Sport
less expensive and less well finished model based upon the N. Record geometry...

1974:  first edition Rally
To many minds, the best all round touring derailleur ever made.

1980: Model 980 worked amazingly well for an econo design.

1982:  new Rally  
with a different body, no longer slant parallelogram (less effective design)
