I am trying to determine which model my very old Columbus acoustic is.
I bought this guitar in a second-hand shop in Brighton, UK, back in 1977 and I'm pretty sure it's been out of production for ages. I tried to search the Web, google images and all but with no luck. The sticker inside just says:

Model no: <blank>
Made in Japan

I'm attaching a photo. Unfortunately the size limit for images on this forum is very low, I hope the image displays clearly. Otherwise let me know and I can send a better resolution image.
If anyone recognizes this model and let me know I would be immensely grateful.
Thanks very much in advance
