Sometimes you do find unmarked brand name items and this is one of them, as this piece Is Identical To The Marked Pieces I Have.  Possibly they did test runs just to see how they worked in the molds or how they were accepted by the public.  This antique toy kettle is in great condition, incuding the original wire bail.
