In that documentary from the late 1920s of the Philco factory, there is a segment of the cabinet shop building teh very cabinets that we are talking about. They had some sort of jig and were cutting the grilles out with an early form of straight sided router bit mounted in a mandrel almost like a drill press. It's bee a while since I saw it. The legs are likely more uniform in that they put square stock in something like a duplicating lathe, but the cutters were spinning as the legs rotated past them. I had always wondered how they could turn out splindle legs in such quantity, I'm not sure that the modern lathes work that way.
