Some nice bits there and in great condition.
However, they're not 1st generation (1992) Ergo, they're from 1993 (so 2nd gen.): 1st gen. had a unique triangular end to the brake lever and in 1993 the body used carbon fibre and had "carbon" written above the lever/below the hood.
FYI the brakes are 1994: Delta before then and in 1995 Campag started putting groupset names on components.
If you check the back of the cranks there's a date code.
The real puzzle is the rear derailleur: the "knurled" cable adjuster is the earlier type (1991 and earlier), where as that type of cable clamp nut was introduced in 1992 and not used by Record.
I trawled the catalogues on the assumption that either the adjuster or the nut was a replacement and my best guess was that it's 1992 Chorus with an older cable adjuster. Record used a different type of cable clamp with a tabbed washer, which required a locating hole in the body of the derailleur below the right-hand limit adjuster screw: you can see there is no hole in the body of yours, so the clamp nut looked to be original.
Not an entirely satisfactory answer though: I'm not even sure the older adjuster will fit and although I can imagine using newer parts as a replacement on an older RD, old parts on a newer one seemed the least likely scenario.
So I had a look at Velobase: usually my last resort, due to it being UGC so only as good as the people contributing...
However, I think it came up trumps this time! Campag did make RD which had both the "old" adjuster and the "new" clamp... their off-road/MTB range!
Long story short, I think you have a 1991 Centaur RD (it was available in long, medium and short variants and also in the usual finish); possibly 1992, but Campag produced a Road and an Off-Road catalogue that year and I only have Road. 1991 catalogue here.
