This guitar appears to be an Oscar Schmidt, possibly sold under the Supertone brand name. It could date anywhere from the 1890's to the 1920's. This close up of the face shows the the binding around the spruce top and soundhole and also the fine European marquetry (wood inlay) which was typical of higher end (and some lower priced) OS instruments. The fingerboard is ebony, while the bridge is maple, which has been stained to resemble ebony. The back, neck and sides are made from mahogany. The slotted peg head is faced with rosewood and sports a 5 pointed star inlay which was typical on OS produced Supertone guitars. The oddest thing about this instrument is that at some point, for some reason, someone decided to cut down the depth of the guitar by removing the back, cutting off about an inch all around the sides and then putting the guitar back together. As can be seen in this side view, the maximum depth of the body (at the foot) is a little under three inches! Not surprisingly, this affects the sound of the guitar, causing it to have a reduced bass response but an added presence in the treble and mid ranges.
