I picked up a Tomy U.K. R.A.T.S. Spitfire which was missing his arms. So I designed some in Shapeways. Unlike the original, these have moving elbows and wrists. These arms also work with the other decos of this mold like Starriors Deadeye and Warugasu and the knockoff B/O Space Dinosaur. https://www.shapeways.com/product/TCRXKUVE4/deadeye-articulated-arms Trivia - Did you know the RATS sold in the US mentioned on the box that they "play with" Transformers, GoBots, Masters of the Universe and Tribots? They do. Sort of makes them one of the first "third-party Transformers".
