Bought this today. A bootleg of the Black Ox from Tetsujin 28 FX. Compared it to some pictures on the internet, and found it to be quite similar to the original with some minor simplifications... And it is DIFFICULT to find pictures of it on internet. Most joints are tight though, and the colours are almost the same as the real one's.
Transformation is simple, but the jet mode is not nice, not nice... I saw a nice graphical render to portray the jet mode, but to achieve the artwork's jet shape, the wings need to be reversed to point in the other direction... or rotate the waist?... wings are small in the first place... anyway, might just make new and bigger wings..
