Again learn to read (and spell).
In the context of MM, all MM machines were sent to Japan at the same time in 1997. As they were unloaded they were all affixed with a Taito metal plaque on the right hand side of the headbox in the same location.
This is fact, not some third party my best mate internet anecdotal garbage from 10 plus years later.
Whatever you think mate, whatever u like to think. You go for it.
I see u must have been there in Japan to see every machine unloaded, I forgot that. ;)
