Conn vintage Japan 70's C-20 rosewood back and sides classical?

Here we have what I believe to be, from a good patron who pointed out what model it was,and how to research a Conn C-20. Made in Japan in the 70's, select spruce top and rosewood back and sides. I looked it up, and it seems he is right, but please do you own research. Has some dents, dings and scratches but plays well and sounds good. Why buy a new Chinese when you can have a vintage Japan for the same price??
