Ned,I ,ve read it on GUITAR ENCYCLOPEDIA book(great!) by Paul Day and Tony Bacon.I can send you this page if you want.This is a Tokai history,but a little brief.
I talked with the folks over at Robin Guitars and yes the early Robins were made by Tokai starting in 1982 (1st yr for Robin) till about mid 1983, I'll be getting detailed info soon. If you head over to robinguitars.com the 1982 catalog features the Tokai made guitars.
