You may want to follow this seller.. His dad p***ed away last year, and it looks like he is starting to sell his dad's stuff.. Most everything is pretty rough, but tons of 55/56 stuff, a couple of sheds of parts I haven't ever seen, etc.. Dad, up to his parting had plans of restoring them all. http://www.ebay.com/itm/1956-mercury-/182427260196?hash=item2a79831524:g:dd4AAOSw2xRYgNGn
That 51 Victoria might have been worth something, but stored over dirt? Probably a rust bucket underneath. Don't know about these guys who are gong to restore the car "someday" and don't store them properly.
