Hi guys
The neck is definitely NOT Tokai. 22F with TR adjuster in headstock - wrong!
Body could be possible, but the absence of a stamp makes me wonder.
Some of the Limited and Custom Editions, the SD series and several others made after 1986 did route for HSH combination - the 3rd number was the pup configuration ( eg: SD651-SSS ; SD652-HH : SD653-SSH). It was faster to route for all 3 configs than to do it one-by-one.
I owned an M2002 - All carbon Strat, 200,000yen and HH EMG pickups. Route was 'swimming pool' style. Output jack was LesPaul placed and the battery was mounted in the Strat output cavity, same as the body your looking at.
regards
