Campagnolo rear mech I'd..?

[vcballbat]

Hi guys, any ideas what model and year this Campagnolo mech is..?

Chorus 92-94

It's got a hidden pivot bolt, more likely to be a Record from before the addition of titanium pieces, maybe a RD11-RE

Chorus from 93 onwards also had the hidden pivot bolt. But the sleeker, more sculpted rear ‘knuckle’ suggests this one is a Record

 

[KermitGKona88]

Completely missed the lower knuckle as I was looking at the main body shape, Record seemed more curved and deeper cut on the main pivot plate, so that was why I thought Chorus. Campagnolo are buggers for not marking these things more clearly.

However - looking closer I realise that the cable grip is a nut, which I think makes it a Record RD-21RE

This looks like it's the one, my cable clamp can use an Allen key or spanner and has been upgraded with Tacx sealed bearing jockey wheels I'm guessing because of the change from ball bearings.
I'm not too clued up on later Campagnolo so many thanks guys for all of your input ..
