Agree with all comments, I think they all have their place in collections! But yes, there are differences not only in the base between the generations. See also the design on the chest of the uniform.
No matter, the Dragon gun is still my favorite set!
Anyhow, no matter really Mark, as I think we have conversed in the past, Trophy is not a straightforward "catalog" like other makers. Even the same set in the same generation could come in 3 different size boxes!
Also, boxes are nice, but in my opinion, if you collect Trophy, the thrill of finding just the pieces intact is a plus in my book. It is nice to find the boxes, but if I find a set I have been seeking, I don't care as much about the box at that point!
