Michael, I am by no means an expert on these things, but my understanding is as follows: the Martin 21 series marries the tone woods of the 28 series with the appointments of the 18 series. So, for example you get the appearance of a D-18 and the tone woods a D-28. Why the “special“ designation? I believe the answer lies in the presence of the pyramid bridge, the wider nut, and the wider bridge spacing and the herringbone Rosette. Possible other features which distinguished this model from the dreads in the standard line at the time it was made. They have made this model intermittently. Here are the specs. Low profile neck shape. 1 and 3/4 nut width.
