I just bought a $80 Mansfield acoustic Gibson Dove copy model 693 the first 2 digits of the serial number is 74 so I am guessing it could be 1974?? Looks exactly like a gibson and appears to be solid rosewood back and sides, spruce top, mahogany neck? It needs a little adjustment but sounds fantastic. I wish I new more but sounds just as good as a $2000 guitar.
