Campagnolo Centaur/Euclid? Help identify.

[Dionarap]

I have some Campagnolo components: bottom bracket rear derailleur and cranks. I would like some help identifying the group set and what year they are. (probably not the correct forum, but some idea of what they might cost) Thanks for the help.

Mech is Olympus, kinda hard to tell what the chainset is from that angle though!
