So the top of the right hand of mine just broke off sitting on the shelf. I looked at it and the piece that broke is a thin grey plastic rectangle with a piece that connects to a spring on the inner hand. It reminds me of mp-09 rodimus shoulders all over again. Wonder if planet x would send me a replacement piece. Either that, or I could try to make one from wood. I can't figure out why there is a spring. The piece seems to be needed to rotate the top of the hand, not pull it out or put tension on it.
