Over the last 20 years I have picked up the "unreleased" stormtroopers from ebay and forums with the intention of building a squad.  HOWEVER, I now believe these all to be recast.  There were going to hit the melting pot, but I ended up making them into fun little fake toy card backs for use as fun gifts.  I have two left and rustled them out due to my own interpretations I made as minis.
