Tom, I think you are looking at too many replicas. People have done a lot of versions depending on the refs they had at the time or what they interpreted from unclear photos of the prop. The photo that Teecrooz posted are the clearer I have ever seen. Not too long ago, a lot of things were still unclear about the macros. and some things, like the weird end of the female EIAJ plug is still undefined.
don't go crazy, just follow the last photos that have been posted and the last informations that surfaced in this thread and the other long one
cheers
