Looks like a nice frame with some reasonable Japanese components on it. The seatpost looks like a 3ttt, not incredibly desirable but different and somewhat unusual.

I don't know what to say about parting it out, except there seem to be 2 types of vintage bike people; those that part them out and versus those trying to piece them back together.

Personally, I like to see an old bike remain a bike rather than a bunch of parts.

Sell it whole to someone who with love it as is, why not?
