The HD12-28 is a 12-string dreadnought from the Standard Series, in East Indian rosewood and spruce with bold herringbone top trim and abalone Diamonds and Squares Long inlays. A 12-string doubles every course; this one has 1 13/16" at the nut, Golden Era non-scalloped Forward-Shifted X Brace and a 24.9" scale, which makes it easier to fret than a 12-string on the full 25.4".
Martin aims it at both strumming and fingerpicking. For a 12-string on a 17" Grand J body with an L.R. Baggs Element, look at the Grand J-16E 12-String; for the six-string version of this trim, the HD-28; and for six and 12 strings on one guitar, the Grand J-28E DN.
