John said in his seminar on Saturday that he had one of the models in his closet collecting dust and that the model was two pieces with one arm being a separate piece. He talked about one being painted gray for the hologram and that he painted the other green for himself. I don't recall why two were made. The seminar was recorded at Louisville and will probably be made available somehow.
Sorry if this was already pre-existing knowledge. I did not read all the posts in the thread.
