Campagnolo bottom bracket - early 90s?

I am trying to identify the model and value of this Campagnolo bottom bracket. This came from a bike with Dura Ace 7400 crankset with STI shifters so that would suggest this is an early 90s model. I cannot figure out the models of Campagnolo at that time, and there is no marking to indicate this. On eBay, the similar ones are listed as $50-60. I would appreciate if anyone has suggestions as to the model or value of this bottom bracket. Thanks!

I believe that the fixed cup with the outer and inner lips was unique to Croce d'Aune, which would place it circa 1988-1991. Hopefully other members can corroborate this.

Thanks for reply. Initially, all bottom brackets looked the same to me, but now you pointed out the design of the fixed cup - I see that there were Croce d'Aune and Chorus that had both inner and outer lips:

Sounds like Croce d'Aune group preceded Chorus group?

Croce d'Aune and Chorus were both introduced in 1988 with Chorus being a step below Croce d'Aune. Chorus did not originally have the lipped fixed cup but appears to have inherited the design, after Croce d'Aune was discontinued.

I just noticed that my link was not specific to the components:

Chorus: VeloBase.com - Component: Campagnolo BB-01CH, Chorus

Croce d'Aune: VeloBase.com - Component: Campagnolo Croce d' Aune

Here's another image of Chorus BB:



I found it very confusing to decipher the Campy components - I appreciate your comments, T-mar! Also, I noticed that some spindles have "A" after "SS", but mine does not. What is "A" stands for?

While the spindle dates is later, the fixed cup with the "ring" of removed material showed up at the bike shop in 1975.
Put a Nuovo Record bottom bracket my new bike that year.
We thought it was interesting and marginally lighter… had visions that they mis-stamped some English bottom bracket fixed cups and did this as a save.

+1 The mat finish and 68-SS spindle are also a match and this seems to be the only Campy BB to have all these elements.

68 is spindle for English BB, SS is for strada (road). Sometimes a letter was used after this for another specific, I think "g" might have been used for triple, but I don't recall A.

The threads on the axle surface of the cup are unusual and I don't know the significance of those. Measure the spindle length and if you sell it make sure to note it. 111 mm if I recall is the length of late 80's double spindle.

$50 is about right for eBay if the cups are in good shape.

Bikes: No-name LH drive track. Also ride an Exxon Graftek, a Masi, a Trek R200 or a RR Boneshaker for fun!

The "threads" cut into the cups at the axle interface were intended to move dirt away from the bearings as the spindle rotated.

So... what's a Dura Ace crank doing on a Campy BB?
