Here's a great early example of how Martin homed in on the reissues of their earlier models that eventually became the Vintage Series. You could summarize this as an HD-28 Plus, as along with the herringbone top trim, small maple bridge plate, and scalloped top bracing of the HD-28, it also has the faux tortoise pickguard, aging toner, and "diamonds & squares" fretboard inlays of early 1940s D-28 models. The "1833-1983 150th Year" stamp on the interior back strip shown in photo 16, btw, was unique to that particular year, and since Martin's production was very low during the "guitar drought" of the early 1980s, not many guitars have that stamp. This example is in excellent and original condition, with no cracks or repairs (only minimal fret wear), and delivers that classic Martin rosewood Dreadnought tone and lots of it. Case is of the same period as the guitar but probably was not supplied by Martin in 1983.
