As Mark said, it's first generation C-record. However, I don't think these versions were standard throughout the '84 to '87 period that he refers to. Your front derailleur is a very early version on which the lower inside pivot is at the same height as the lower outside pivot. This made the derailleur oddly tall and required that the braze on mounting bolt be attached low on the main body rather than threading through the upper inside pivot as it later would. Soon after the intro of C the lower inside pivot was moved down to a position behind the chain cage, giving the derailleur the same basic geometry as a SR/NR braze-on. This permitted a more conventional mounting arrangement while still allowing the standard position of the braze-on. The clamp-on model retained the high inside pivot.
The rear derailleur you have may have the tinkery spring-loaded mounting bolt that was supposed to speed up wheel changes. A lot of tehse broke and Campy reverted to an ordinary NR/SR setup soemtime before the (1988?) "redisign" that added the pulley cage cutout and script logo.
Anyway, these are pretty much the only C-rec derailleurs that aren't technically "off topic" for CR.
