the only information i can find is that the sticker in the soundhole looks like this:
...except the serial number is something like sk67??, it doesn't say "made in japan" and there's no number below it. the number is very, very faded - so faded i can't entirely make it out.
that picture is from a 1978 model, and that label is 70s era, roughly.
i like having weird guitars like this, on top of normal guitars like the gibson/epiphone and the fender/squier. the black epiphone is weird, i'm going to make the rx40 weird and i want my 21 fret classical to be weird, too. i want my p90 and jazzmasters to be weird. weird weird weird...
