tmont,
In '84, the D-50 would be solid rosewood back and sides, sitka spruce top with straight braces, ebony fretboard and bridge, with the older, "domed" headstock (as opposed to the tapered or snakehead headstock introduced in '87). Scalloped braces were also introduced to the D-50 in '87.
In '83-84, Guild also made the (short-lived) D-52 model, which was basically a D-50 with scalloped braces. Note that some of the DV-52s made during the first year of production ('93) were mis-labeled as D-52s. These mis-labeled DV-52s are distinguished from "real" D-52s (from the 80s) by their snakehead headstock.
I created a spreadsheet/list of (most) Guild dreads made from the Hoboken/Westerly factory's, which I posted as an
LTG "blog"...
