The articulation on the Luke is done by using an arm from a GI Joe and attaching the forearm from the Bespin Luke. I have not yet tried to use the new Joes yet, so all the GI JOE parts I use are vintage.
Thanks for the kind words! BTW, I was just about to write you back. I am out of casting resin, and my wife is getting me some for Christmas, so if you can wait to trade I can do it later! Your email was really nice.
I saw one of those Dath Tater T-Shirts at WalMart one time and almost got one!
Thanks again for the compliments!
