Here’s a 2014 Martin Authentic 1931 OM-28 that has opened up beautifully, in very nice shape for its age, three small dings in the top down by the lower bout on the bass side (see photos), but otherwise very clean. Adirondack spruce top with Martin’s VTS (Vintage Tone System) applied to both the top and the adirondack spruce braces. Back and sides are Madagascar rosewood; the bracing is the Authentic 1931 pattern. The solid ebony fingerboard features diamond and square inlays; the ebony bridge is the Authentic belly style with a long saddle. Tuners are Waverley nickel. Martin’s thin vintage gloss finish. ¬†Note that the Martin logo is absent from the Madagascar headstock on the Authentic 1931 and is instead embossed into the back of the headstock. ¬†Full specs below. Terrific OM.
