I've only seen that cabinet style with hex knobs...but given Philco's penchant for using up old stock before moving on to new (example: that brass escutcheon on your set which was leftover from older 60 models and was soon replaced with a bakelite escutcheon), it would not surprise me if they may have used rosettes on some early production models with the brass escutcheon.
