OVOID AMERICAN EAGLE JUG

This jug is a real cunundrum.This is my first try on this site and am hoping for an opinion on this piece.I have sent pics. of this unit all over and no one as of yet can come up with a similar item or its origons.Decoration is under glaze and true black,parting line in center so its hand tossed not cast.Handle is offset it IS A LEFT HAND jug!.Glazed on inside also in black,clay that was used looks pretty white compared to what is locally used in Ontario.The jug has no chips or cracks which is not uncommon for a collectors jug, I was going to ''chunck'' it to see if its stoneware but didn't.Sent pics. to a couple of Antique Roadshow guys they feel its legitimate and not a repro. but without another example seen they cant really establish its origons.Has anybody ever seen another like this.Some people think the bird is a family crest and not a revolutionary eagle.I figure its a whiskey jug.Found in southern Ontario Canada.
