We already have an answer from Tokai Japan. They've been really quick. I sent quite a lot of pics and here's their feedback:
As long as I check the pictures, I can say the model is one of our PB series before 1983.
It has 4 screws machine heads, thus it seems PB50/PB60/PB70/PB80.
Color Metallic red is applied for these models, I am afraid it is more than 35 years ago, it is too hard to discern the model.
But I think it is real Tokai.
One concern is that Neck Plate suppose to have Serial No.but I cannot find it out.
Japanese letter express the color, others could be some kind of lot No.
I hope the info helps you.
Best regards
Tokai Gakki
Negative: they don't know the model or year of production
Positive: they admit it's a Tokai
