This Used 1956 Martin 00-28G Acoustic Guitar in Natural is here on consignment. The back of the guitar at the lower bout suffered an injury somewhere along the way, and a small (about 1"x1") square of wood has been replaced, as has a strip of binding along the same area. The top of the guitar has one long indentation on the treble side, there is a similar mark on the back as well. There is a spot of unusual finish wear on the bass side of the back, possibly due to a chemical reaction with the finish or perhaps from getting a little wet there.
