I think the Vincent world along with many has changed........When you see multiple Comet crank cases for sale on ebay at crazy low prices, and none of them selling........A few years ago, bidders would have been fighting over them and going for big prices.......It seem to me that people are after bikes that can be ridden now.......not take the next 5 to 10 years to restore and get back on the road.......There are folk here in Australia who have been trying to sell off their collections for some time now........Too much money for what actually might be something worth while.......unless you can pick up a "Lot" for next to nothing, i think a lot of these collectors of parts might have just missed the boat........After all this time, i have decided to give restorations away........2 main reasons.......Obviously the cost has gone through the roof, what with parts costs, plating, pianting, machining.......all have become prohibitively expensive, and second, the total time to carry out the job has also gone sky high. All these specialists have become more busy, and so a job that should take 2 weeks, now takes 4 or more. So unless the bike is something really special, i wont take on any more. So for all you blokes with 6 upper frames, and 5 sets of crankcases lurking under your benches........you might just be in for a surprise if you think you are sitting on a gold mine. it is possible things migh bounce back.......Probably as much chance as the price of fuel coming down.
