It's hard for me to gauge, because I remember getting Soundwave at a local market second hand, and owning Hot Rod and receiving an Optimus from Kmart from those red light discount they have when toys or whatever are missing parts. He was missing fists from what I can recall.
Out of those 3, I think Hot Rod is the only one that is the same one, though my original one went missing for a number of years, so I bought a reissue years later because I wanted it. Then time went by and I found the broken part of the canopy to Hot Rod. I kept hold of it, and about 6 months ago, my parents did some rearranging of some cabinets and low and behold, the rest of him was behind it. He is a little worse for wear, but fixed enough for him to display.
