I found these "prototype" action figures stands on eBay. The production version of this stand was released in the 2010 Clone Wars line in a grayish/silver color like in the the bottom photo and appears to have multiple variations. However, I don't recall seeing a clear production version. The seller is on eBay, based out of China. I am speculating that these were made from original steel molds, but not really pre-production. Does anyone else have any insight on this? Were they produced in clear for an exclusive or other line?
