I own 2 Hohner Limited Edition HG model guitars from the mid 1970s. I have an HG-310 which is the Hank Williams ad and the HG-320 and both are Limited Edition "hand made for Hohner" in Japan and both have solid bear glaw spruce tops with solid rosewood sides and backs. I saw an HG-310 haveing a neck reset a few years before finding my 2 guitars and when looking at the neck joint with the neck removed I could see the sides were solid rosewood and the binding was separating near the neck joint on the back side which showed the back on the bottom piece was also solid rosewood(back is 2 pieces on the HG-310 and 3 pieces on the HG-320). I read a sales brochure from 77' for the Limited Edition Hohners that said the bodies were solid and not laminated, but I'm thinking this may have changed as they moved past the 1978 models since I've seen newer HG-320s without the theater ticket shaped "hand made for Hohner" plaq next to the paper lable in the soundhole that didn't say Limited Edition. I've also noticed other Hg-310 guitars with the headstock shaped like the later Arbor models where mine both have the headstock shaped like a Martin with no beveled end. These older HG models are really very loud and have the great tone of a pre 70s Martin.
