Idont know, you may want to visit a
www.teiscotwangers.com for teiscos(japanese) . They have a page full of pictures of every teisco model. It really does look like one of theres. (sorry, this whole teisco guitars research is my new passion.)
But if you say it has a made in korea tag, your best bet is to google search. I did try to find guitars under the Kawai company, but everytime I search on line, all I can find is there keyboards and etc. but no guitars.
I may try a yahoo search later to find out , just because thats something I would also like to know .
