Maybe it’s a big misunderstanding and GJ just wanted it to be from the
Interactive Series. Tilting engines are for the maintenance diorama, when the power plants are taken off the pylon, the whole model tilting backwards on the MLG is for the runway diorama while the aircraft is rotating, and finally the spreading main landing gear imitates a fully-loaded 767-400 prior to a long-distance flight. We just misunderstood what Gemini intended to bring us.
On a more serious note: it’s rather impossible to tell from a single photo – apart from the tilting fuselage, of course. But I would agree that the mould is looking rather outdated and - please apologize - even simple and cheap. I find it interesting, however, that quite many collectors obviously think (or take seriously into account) that a manufacturer makes a new mould, hides it in the model boneyard and dig it out on another occasion. While that sounds like a good thriller plot for Hollywood, I can hardly believe this Gemini 767-400 mould was casted years ago and held back for the moment a competitor is about to release it.
