More information about my HG-07?

I have an HG-07 Acoustic, serial number 07008. On the Hohner International sticker inside the guitar, it also has the numbers 12 77 printed perpendicular to the model and serial number. Can you tell me any more information about the date and country of manufacture?

(I found this for $8 at the local Goodwill – part of the soundhole is broken out and it needs a new bridge, but it has a beautiful tone and lovely easy action…)

Thanks!

The 12 77 is the month and year of manufacture. Your guitar was made in Japan.
