Yeah, the bells are not too bad, but still not full size. I think you will find most of the parts are a few inches shorter than what they should be and I would hazzard a guess the guy wearing it in the photos above is around 6' tall.
I do have some photos of some of these parts next to my TM parts and they are quite a bit shorter. I think it is a shame they modifed and cut these Disney suits down so much because they would have been a great base for an ROTJ kit.
