the ones you're referring to are the red label, nippon gakki, fg models, made in japan, in the late 60's and early 70's. i got into chasing them down for a while. started with a fg-75, that kind of fell into my lap,which is sort of a parlor size, then an fg-110,a little bigger, then an fg-140, and an fg 180, which are dreds. the fg-180 is one of the more sought after dreds. they all sounded very nice. i would recommend any of them, which are structurally sound, as nice inexpensive guitars. anyone looking for the proverbial beater should check them out. i was pleasantly surprised by all of them except the fg-75. it was too small for me. the special ingredient is the nippon gakki label, which is supposed to be the better guitar, but many made in taiwan are just as good, imo. the nippon gakkis aways bring more money though. here are some pictures of the ones i had recently. they are in the same order of the description. all of these guitars were either 70 or 71 models.
