I have an FG 260 that I believe, after reading info here, was not imported. The serial number is 30531 and it has the rectangular tan label marked made in Japan. I have had it for many years now and was curious as to the date it was manufactured.
You are correct about the headstock. The guitar still plays very well. Also have an FG335 I bought back in 1977. Both are used and played often. Love my FG's. Thanks for the quick reply.
