I aestimate Tokai effects beind around mid 80's,you can see a full page in '85/86 catalogue.There are two models : the first ones are 1 series in metalic or black finish and II series with a plastic box.Youes is the first series.
I own a TCH-1 and recently a TDL-1 and I'm very satisfied.
Javelin70 owns several,and Peter Mac too.....
I read somewhere they were built by Pearl but not sure....See http://www.geocities.com/SunsetStrip/Vine/6655/pearl.htm and make a comparison.
