I think that is the only set known of NOS ones, other than another set of red ones I saw on eBay a few years ago, but think those went overseas. I think the ones you have are red (think) but I have a very nice set of blue ones, not NOS though. They are pretty rare cranks no matter what, but you are right, used and NOS in the package is waht makes them a col piece. Just by a very nice set that is already out of the package! That seems to be the catch with BMX and finances - yopu have to buy more than one of every item - one to use and one for display.
