Re: 1978 hohner acoustic
It's not an HH320, they were hand built in Japan for Hohner and had abalone inlay logo and almost everywhere on the body and neck. If you go to the Hohner museum from Google, you'll be able to locate your model. Does it say it's hand made in Japan for Hohner? Does it have a V shaped binding splitting the back center of the body? An HG320 had solid spruce top with mahogany neck and rosewood sides and back on body.
