My brother own an acoustic guitar for years and it's been passed around in the family. I've recently come in contact with it and I want to rebuild the entire thing (it's jus a shell right now) The only problem is I have no idea what kind of guitar it is. I've searched for months and can't find out. Inside it has a small tag that says D-28, which is a Martin model, but the headstock doesn't match Martin at all. Does anyone recognize this or would anyone know how I can find out what Brand/Model it is???? Thanks!
