Bought in 1987 and for sale in 2013. My very old Campagnolo Delta brakes are now under the hammer on eBay. Sold €177.
Bought a year later in 1988 my Jean Paul Gaultier suit is also up for bidding. Reserved at US$50 it's a bit of a long shot, but still . . . .
A few years ago I sold a Campagnolo Disc back wheel on eBay for US$710 it was a very rare and sort after item and luckily for me two bidders went head to head for it - which was nice :-)
