  • Notes
  • The model 20 series marked Philco's first use of the term "Baby Grand," and the term applies to both a cathedral and a small console. There is also a concurrent larger console called the "Concert Grand." After the model 20 series, the term "Baby Grand" was used only for cathedrals.

    There were two versions (early and late) of the model 20 Baby Grand console with slightly different cabinet styles. The late version has a fancy cutout pattern on the speaker grille instead of the simpler opening on the early version.
