I do not believe any of the AD trucks can be considered rare. They were the first major redesign after the war and GM sold a lot of them. While the 47-2 and the 55-1 are probably the lowest production numbers in the AD years, there are still a lot of them out there. I believe a restored 47-2 would not be much more valable then say a restored '53, and may be less because some folks would like the more "modern" features on the 53. Just my .02
