It looks like ThemeParkConnection has just gotten in another piece of Horizons history, have a look at their facebook page here. It appears to me this could actually be the model that was hanging upside down in one of the bubble windows, you know before you picked what kind of journey you wanted to go on at the end. We showed some pictures of them back in this post.
Direct link to their wall photo.
Cant wait to hear what kind of price this is going to go for.
