I’ve recently come across I pretty good source for old catalogue scans for Japan made acoustic guitars. It’s called oldguitar and has about 50 different Japanese guitar brands represented, some brands has more scans than others and most of them are in Japanese but it still pretty nice to see your guitars in old catalogues. Unfortunately I only managed to find my Morris W-40, K. Yairi TG-40 and Suzuki Three-S F-120, my Morris WL-35 and Kiso Suzuki WE-150 seems a bit harder to track down.
Morris W-40 Made in Japan by Terada 1973
K. Yairi TG-40 Made in Japan 1977
Suzuki Three-S F-120 Made in Japan 1976
Kiso Suzuki WE-150 Made in Japan 1970’s
