There are lots of 1982 large tenon Grecos out there with "Super Real" on the headstock. That is probably why people make the claim. Pre-April 1982 are all just variations of medium tenon.
Hello and welcome to the forum!
I'm in the middle of Tokyo which is rather dangerous for temptation in guitar stores.
Those Tokais you saw are actually made in China under Tokai instruction (whatever that means) and probably are pretty decent guitars...
It looks like a veneer to me with its perfect mirror image which should not be there exactly when a flame top is carved from a solid top. Pickup cavity photos are pretty much the only way to prove it conclusively IMO.
I've been busy so haven't kept up with the threads here. I did just look at the catalog and there is no mention o Brazilain boards or Honduran mahogany in the catalog. It is always possible there is some LS-200 with those custom specs of course.
The Greco that is based on has a 1-piece neck without fail. It looks to me like a half-decent attempt at a replica of a Greco, or the neck is a replacement with a new logo perhaps. The screws are all old style screws and the body looks to be SEN ash so it could be an original body with a changed...
That is a Sonix shop model. I think the current 320 is like the old 260 or whatever it was called so not all the bells and whistles. Too bad with that nice piece of lumber on the top!
That is a great example of an early Tokai. The grain is deceiving but IMO there is a body join in the centre as it is with the 60 and 80 models. Tokai were so good with their grain matching it is hard to tell in many cases.
