I don't like to see it either, but this bike would definitely get £500 on eBay probably 20% more for parts. Either eBay is wrong, or buyers are too tight to pay going rate for anything on here! Italian and Belgian frames are obviously big sellers online right now, the Eddy Merckx Telecom colours in this forum would sell all day long on eBay for 8-900.
It seems everybody wants a bargain, but no one wants to pay for quality.
Quality sells. I worked in antiques for five years. The best place to sell quality bikes is in a free bidding market place.
