That’s a D-28. Should be a great guitar. I would check to make sure the bridge is not lifting, check the neck relief and string height at the 12 fret and then set up as necessary. Anything can be fixed and an 82 D-28 is worth fixing. If there’s nobody local, I would contact Brian Kimsey and see if he is taking in new work and ship it to him.
