HI BOB, THESE ARE FROM RT PLASTICS SAMPLE BOOK HERE IN LAS VEGAS ... THEY WERE SAMPLES MADE FOR THE MOVIE PROP MANAGER ... THEY DECIDED TO PONY UP AND SPEND MORE MONEY FOR THE BETTER QUALITY DESIGNED CHIPS ... BELIEVE ME THESE ARE THE ONLY PROTOTYPE CHIPS MADE AND WERE KEPT BY THE MANUFACTURER ... THEY ALSO IMPROVED THE DRAGON DESIGN WEEKS LATER. THIS INFORMATION IS FIRST HAND BY THE RT PLASTICS. HOPE THIS EXPLAINS THE DIFFERENCES ... RICH BURGEL ... 100% GUARANTEED LEGIT ... THANKS FOR LISTENING ... RICH BURGEL
