Tomorrow is the release date for the HGCE "Gouf Ignited," which is based on the anime and not the HG SEED based on the design drawings.
-- Taking advantage of that, I'm going to post a modified Gunpla of the old "Gouf Ignited" kit, which, like the Legend, will likely see a drastic decrease in demand due to its rarity (lol).
Schwalbe Gouf Ritter
Using the torso of the "Slash Zaku Phantom" collection kit, (with its double ball joints in the shoulders, which allows for good movement), it has the original polycaps "PC-123+" but now features pull-out shoulder joints, a rotating waist (lol) despite being a Gouf, and a skirt thanks to modified pipe connections.
