John McVie's old continuously fretted bass. :-)

Thanks for posting Jazzy. Makes me a little wistful to see it hanging there. I hope somehow the original Chain bass could end up somewhere it will be played again. 

The auction site has pretty good pictures of John's Custom, and a decent write-up. (skip down to 'lot essay', and 'read more' part...)
