Hi guys I've read quite a lot about G1 OP and the colouring of his roller, but I am still a bit confused. I'm hoping you'll be able to help out. Some months ago I bought a big lot of old and new Transformers. Among it was a G1 OP with a grey roller. Initially, because of the good condition, I figured it was a re-issue. But then I saw that my own reissue has a blue roller and started doing some reading. Still confused, though. Did any reissues come with the grey roller? And if not, is my version anything out of the ordinary? Thanks in advance, guys.
