I am finalizing the restoration of a Cuevos "Signature" bike equipped with a 3rd gen Z2000/2001 gruppo (RD has a big "Z" on alloy body). Although I do have a good one that works fine it has a scrape on it and, as mentioned before, I am doing a restoration. I want to clarify the 3rd gen thing... in my eyes the 1st gen was a Criterium derailleur with a drilled cage and a slot milled that obliterated the Criterium name and the 2nd gen was an investment cast steel body with 2 triangle holes in it.
There is no need for an NOS item and you can even keep the upper Ti pivot bolt since I'll use the existing one but it does have to be unmolested. Send me what you have with a price and maybe we can talk!
