OK, with apologies for not having had time to clean it properly; the chain, in particular, is a disgrace!
The Campag QR hubs:
The other Special feature was the lug linings. They missed a bit here, though...
The bars, like yours, with an SR stem:
The Shimano 600 rear mech. I think the pimpled part originally had a black background; that's what the levers suggest, at least:
Replacement crankset Shimano 600 ax with big fat axles and weird pedals (I have a spare set, plus the toe clips)
Saddle is a recent addition (thanks again, Tim Coward!) and the seatpost may well also be new. It's an easy Allen key adjustment, so maybe I got rid of the tricky one you mention,
