lots of nice bits
Never seen a long cage campag rear mech like that, looks very "tourist"
Campagnolo's first dedicated rear long cage"touring"mech was the Rally
, based on the Nuovo Record. I believe it was first introduced in 1972.
I have one (version 2), standard fit, on my 1978 Holdsworth Mistral.
I'd keep the Claud Standard.
