I think that the first Philcos with knobs function decals may have been the 1937 line of sets, the 1928-36 models did not have them but the 1933-36 models did have the "Philco" block letter decal on the front panel. Some companies had the control function engraved into the knob itself depending on the model and year, Silvertone, Detrola, and Stromberg Carlson used to do this.
