I have the following for sale.
Campagnolo Chorus Chainset. I believe this is a later 8sp. It has the self-extracting nuts. Very nice condition, threads and tapers are clean, bit of shoe scuffing on the cranks (looks worse in the photos than it actually is) but the logo on the cranks is clean. 170mm. Chainrings have had some use but are still good and have decent life left in them. £25 plus postage. Needs a standard 102mm campag bottom bracket.
Campagnolo Veloce Bottom Bracket. New and unused. 111mm english thread. £10 plus postage.
Campagnolo Athena (?) Bottom Bracket. Also english 111mm. This is the old style adjustable version. Looks tatty and there is some pitting on the body but the bearings themselves are in excellent condition and it runs very smooth - decent life left in it yet! £5 plus postage.
