I wouldn't put it past someone to fake one but it would seem a lot of effort as theres a fair few around. You can get them on the sprues or made up. There are even some graded ones around. Aren't they UZAY's rather than Polish :?: I can't remember with bootlegs.
I think they may be Uzays, Gusties got one made up. I've had a few polish off Steve, and I think they may be a diferent material. NOt sure till I get it in m y hands.
I've never seen one sell as an Uzay, i think you guys are getting mixed up with the Uzay sprue that gets sold off as a prototype all the time, I think you will find that they are just overstock as well though and not proto, same with the Polish stuff, all overstock apparently.
Out of the second generation Polish bootlegs, all but Vader has turned up on these sprues. The others have shown up in various quantities and various colors (i.e., Nien Nunb molded in gray or blue, etc). Personally, I've tracked down all but Leia. Still pissed I passed on one when I had the chance but that happens sometimes. Makes the hunt all the more fun
PS The seller is top notch. A+ all the way. [Tell him I recommended him to you!]
