I was just looking at that here:http://www.tf-1.com/articles/jtf_frame.php?art=sixliner
and was about to say how close in moulding/transformation Joe and Windy are haha. But yeah, the aesthetic of the train mode is very different, even if they occupy the same spot in the combiner and have the same transformation. Even the chest and torso area look very similar.
Do you think it;s worth adding something in brackets after "Sporting a repainted TGV locomotive, Japanese style bullet trains..." ?
EDIT: Also, if it's technically the same transformation, same function as the previous robot and shares much of the inner moulding if not the outer shell...does that not qualify as "retool" or "remould" ? I would think that mentioning it is an entirely new mould would imply that it wasn't based on the previous "Joe" figure at all, even within a relative Micromaster sense.
All the best
