Has anyone stripped/rebuilt an old campag rear derailleur

[aea730]

I’m just building a Gios Torino in period Super Record, I’m steadily working my way through all the parts cleaning and polishing.

I keep picking up the rear unit and putting it back down again. Now I’m quite good with this sort of thing but don’t want to be left with a parts tray full of springs and bits I’m baffled over.

Has anyone embarked on stripping one of these....or even better, successfully re assembling
