It seems to me that for a lot of people here their passion for vintage bikes isn't so much about possessing said bikes as it is about keeping those bikes alive and on the road. So if I've got a part in my garage that I'm not using (and I can find it), it would have more value to me in the hands of someone else who needed it than it has for me on the shelf. A lot of the stuff I've got is still on the shelf because it's not worth the trouble to me to do all the work to sell it, but if I hear about someone who needs it to finish a better case for packing it up to ship out.
