Here is a picture of a very rare Campagnolo chain tensioner from 1955.

Here's Campagnolo's ultra rare first version of the Nuovo Record rear derailleur introduced in 1967. The box is very rare and was used in 1967 - 1968- It warns the user that the chain must be long enough to fit when on the largest chainwheel and the largest cog.

This picture shows the words, "PATENT CAMPAGNOLO" near the der hanger. This seems to only appear in 1967.

Note that the pivot stop is carved into the knurled barrel- very elegant and exclusive to this very first version! Later in 1967, a "grub screw" pivot stop is attached to the knurled barrel. Also note that the spring notch on the lower pivot is in a different position from all other years- it is centered in the area between the rivets.

Here's the 1968 version of Campagnolo's Nuovo Record rear derailleur with it's original box . 

Here's the same derailleur- note the unusual smaller plastic pulley wheels with only 9 teeth. This is typical of the 1967, and early 1968 models.

This version says "Patent" on the top- but there's no date next to it. This is typical of 1968, or 1969 models. Clearly there were many transitional features between the very earliest versions of Campagnolo's Nuovo Record rear derailleurs.

Note that the pivot stop receiver is brazed on to the knurled barrel, rather than being part of the casting. This is typical of 1967, or 1968 models

This is the back of a Campy Gran Sport rear der. This version has black oxide mounting and pivot bolts and a threaded cable adjustor. There are no holes drilled in the pulley wheels. Note the "Open C" and "G" in "CAMPAGNOLO". This is an early variation. 

This is the back of a Campy Gran Sport rear derailleur very similar to the previous picture, but the "C" and "G" in "CAMPAGNOLO" is the later, more common closed variety.

Here's a picture of the front of the 2 varieties shown previously. The upper derailleur is the older one. Note the much cleaner forging. This may simply be a result of the forging dies being newer with less wear and tear.

Here is a picture of the same two derailleurs showing the "spring covers". The older derailleur is on the right and has the shallower 4.5 - 5.0 mm spring cover.

Here are the same derailleurs showing the decorative reinforcing points. The one on the left is the older one and has slightly longer points, (the picture doesn't show this well)

Note that there are more lines inside the "World", and the exaggerated loopy "L" in Campagnolo. This is an earlier version. This loopy "L" can also be found on very early shifter clamp bands, and perhaps other clamp bands.

This is a more common later version. Compare "L" s and "Worlds".
