Flying Ducks, Geese, or Swans Bronze Book Ends, Bradley & Hubbard?, Hubley?

This auction is for a pair of heavy metal, I think bronze but could be iron, vintage book ends. Together they weigh over 5 pounds. There are flying ducks or geese or swans over the moon with the ground below. On the back they are lined and both have the number 9688 at the bottom. I don't know which foundry made them. It could be Bradley and Hubbard or one of the others. They are lovely with an excellent patina. If you take the buy-it-now, I will ship them for free within the U.S.
