I think that the trainable launcher needs redraw, its mounding seem to be two pyramids with square base, with chopped top. I am not sure also if the early Barak had fixed or folding wings (also not sure for late Barak 1 either). Comparing with Sea Wolf, Barak 1 is bit longer, with smaller diameter and larger wingspan. Personally believe that the experimental trainable Barak 1 launcher was comparable with GWS-25 Sea Wolf (concerning boxes size).
