A truly special piece. Only 73 of these were made… fewer than the vaunted D-45 model. This was also the MOST expensive model in the entire Martin catalogue. Brazilian rosewood back and sides. Very fancy inlays including the vertical “C.F. Martin” logo on the head stock. The vast majority of these guitars have been converted to an OM style. This one has not. The best sounding archtop I’ve ever heard!
