This 00-18 hails from the golden period of Martin production, and sports a very rare “shadetop” finish to boot! Period specifications include an Adirondack spruce top with scalloped forward-X bracing, mahogany back & sides, mahogany neck with 1 3/4” width at the nut, ebony fingerboard with pearl dot inlays, ebony bridge with “through” saddle, and open-gear Grover tuners. The pickguard, nut, “G-100I” tuners, bridge, bridge plate, and shadetop finish are all original to the guitar. The guitar received a previous neck reset and refret- the frets are in very nice shape, but the neck is due for another reset. The top and back are both crack-free; the top appears to have some very old overspray on top of the original finish, the back and neck finish are unaltered. The rims of the guitar have had several crack repairs, and there is some localized touch up in those areas. One crack appears to have been an impact on the bass side’s upper bout; there is a small cloth patch inside in this area, and two small splices in the bass side’s lower bout area. There is a long crack on the treble side’s lower bout area which was cleated, and a couple smaller cracks that were glued. The endpin was also enlarged at one time, and subsequently plugged and re-drilled. The original bridge suffered a crack that was able to be repaired; the original bridge plate is in very nice shape. Comes in a hardshell case.
