I have an older classical guitar that contains no headstock marking or internal label. Its machine heads (which I had to replace) were closer spaced than modern machine heads - pre-1960 according to a luthier. My luthier suspects that this may be an early Yamaha Nippon-Gakki but is unsure. My email address is peter.dwyer03@gmail.com. Thank You
Hi: I have a G85 GAKKI Yahama # 373415 I purchased it in 1965 in Los Angeles from an importer. Any more information? I have been playing it for many years. I live in Northern California USA
