Hi syrinx,
actually the SS series is CBS Fender - whick started in 1965, but began using the larger headstock in 1966. The vast majority of SS models are the 1976 3 bolt style with a 1966 4-bolt style being offered as the SS-60 through to 1983 (7okai) when the SS-60 and SS-80 were both a 4-bolt neck style (Tokai)
The ID chart on the main page was made by me for use on this site just after I first joined and is really meant as a logo guide rather than a model guide. I went more for the most likely encountered logo than just the rare ones as 3 years ago correct info on identifying Tokai guitars was very scarce on the ground.
With the help of some fabulous people, Ned has been able to turn the site into a recognised and factory endorsed site. Not a lot of Internet sites can boast that.
regards
Peter mac
