1840's Martin & Coupa Alternate X Braced Spanish Style
This Martin has what I believe may be the first experimental variation of
X-bracing,which appears at about the same time on a handful of Martins and
Schmidt & Maul Guitars.
One such Schmidt& Maul is dated 1845.
This example, which is quite close in size to a standard Size 2 Martin,
also foreshadows a standard Martin Style 21, with simple, tasteful
appointments including a herringbone
rosette and back strip and a top border consisting of simple light and
dark lines. The back is rosewood over mahogany veneer.
