What is the story behind this one?

Well this topic over at RS should help you out a bit.
Not sure if it helps or makes things worse.
I have never heard of this version before myself. However, I know the seller has been on ebay selling vintage Star Wars for a few years. She seems to buy up lots of vintage stuff as well. From her pictures, she has a lot of the harder to find items. If this is the stuff she sells, I can't imagine how pristine her own collection must be.
