Tokai Japan produced "no serial #" Greco EG models during the same late 1980's - early 90's time period as Cort Korea, and beyond. This was omitted in the initial Greco portion of the FAQ, and has been confusing to some. 1- The most telling differences between the two are cavity routes. Korean made Cort Grecos always have 45* angled pickup cavity corners, (blue arrows) while Japan made Tokai Grecos have standard MIJ squared corner pickup cavity routes, (pic #4 below) Pics posted below of both Greco-Tokai Japan produced and Greco-Cort Korea produced examples. 2- Tokai has consistently used squarish end tab pickup routes while Corts have the more common oval end tab routes found on other Grecos. Tokai made Grecos I've seen, have medium to medium-long tenons and a 1/2" wide tenon route. Later Tokai made Greco models may, or may not have a longer tenon and tenon route, I'm not sure. Cort tenons are always 1" or longer, with the tenon route extending to the bottom edge of end tab routes (black arrows). 3- Tokai switch and pickup wiring runs through a rectangular channel routed into the back (angled from the switch to the control cavity) while Cort switch and pickup wires run through a round hole drilled between both pickup cavities. Wire paths used are consistent, and different, for both makers (white arrows). 4- Cort pickup cavities are color coated, while Tokai pickup cavities are clear coated and stamped.
