Campagnolo Record (RD-19RE) derailleur

For the 1992 model year Campagnolo finally launched a Record derailleur with a concealed p-pivot bolt - catching up with the look that Shimano had introduced with the 1986 Shimano Santé. The new Record was a broadly satisfactory object, with a fine finish, a certain solidity and reasonable indexing performance.

However, at its introduction it weighed an elephantine 260g, compared to around 190g for the Shimano Dura-Ace 7400 series. Campagnolo put the Record on a diet for the rest of the 1990s introducing a series of incremental improvements, each marginally lighter than the last.

I am aware of 9 possible variants. A listing of them, with probable dates, might be:

RD-01RE, from early 1992, had a polished, cast, inner pulley cage plate.
RD-10RE, from later 1992, sported a stippled, pressed, inner pulley cage plate with a simple shape around the tension pulley.
RD-11RE, from early 1993, featured a stippled, pressed, inner pulley cage plate with a pointed extension at the tension pulley.
RD-11RE, from later 1993, had a stippled, pressed, inner pulley cage plate with a spoke protector flange. Logic would suggest that this should be RD-12RE, but, confusingly, seems to be called RD-11RE.
RD-21RE, from 1994, saw the introduction of 8-speed pulley wheels with a self centring guide pulley.
RD-31RE, from 1995, sported the word 'Record' on the outer parallelogram plate.
RD-41RE later coded as RD-08RE, from 1996, featured the words 'Record Titanium' on the outer parallelogram plate.
RD-09RE, from 1997, had the words 'Record Titanium 9 Speed' on the outer parallelogram plate and a steel cable clamp washer with a single 'prong'.
RD-19RE, from 1998, also had the words 'Record Titanium 9 Speed' on the outer parallelogram plate but had an aluminium cable clamp washer with two 'prongs'.

I believe that this example is an RD-19RE, the eighth iteration of this basic design. I believe this because it has 'Campagnolo Record Titanium 9 Speed' written on its outer parallelogram plate and has a 'two pronged' cable clamp washer. Like the RD-09RE, it is often called a 'Record Titanium 9 Speed'.

You will also have guessed that this is an 9 speed derailleur.

A list of relevant details might include:

The logo on the outer pulley cage plate is the Campagnolo signature, combined with the words 'Record Titanium 9 Speed'.
The b-pivot bolt and hidden p-pivot bolt are titanium.
The cable clamp bolt is a simple Allen key design.
The cable clamp washer is aluminium and has two 'prongs'.
The pulley wheels are Campagnolo's 9-speed pulley wheel set with a self-centring guide pulley. On this particular example the tension pulley is a genuine Campagnolo 9 speed spare - but has a slightly different part number from the pulley originally fitted.
The inner pulley cage plate is a stippled aluminium pressing with a spoke protector and some extra 'creases' to allow for the narrower 9-speed pulley wheels.

Strangely, the total capacity has increased from 26 teeth for the RD-08RE to 27 teeth for the RD-19RE (and RD-09RE). This is odd because the geometry of both the parallelogram and the pulley cage have remained the same. Well, they do say that space is curved...
