Apulian rhyton from the Medici Dossier

There is an image of an Apulian rhyton in the Medici dossier of some 4000 photographs. The piece is in the shape of a goat's head with horns painted white. A crouching Eros, holding a fan in his right hand, is shown on the neck.

This seems similar to lot 104 that is due to auctioned at Christie's next month. The Christie's rhyton surfaced at Sotheby's in New York in 1994. Who consigned it to the sale?

There are major implications if the two rhyta are indeed the same. Was Medici consigning antiquities via New York in the same way that he appears to have done for London? What was the scale of this activity? Where are the pieces now?
