Dyna Gakki, or so I was informed when I sold my last one. I knew about Tokai and Fuji Gen, but I had never heard of Dyna. I did some research and it does look like they were yet another source....
See my post above from 2007. Sticker on the back of the headstock? Nope. Sometimes a date can be approximated from the headstock shape and decal. There' s a website out there somewhere that helps with that. I reached out to them after buying my first and they said there is no record. Fernandes farmed out production to many factories.
