Fan, Dugan
Mostly seen in the footed gravy boat shape (sometimes called sauce boat or occasional dish) shown at left. The interior is plain. The only other known shape is a 6-7 inch bowl (on the right). It could be that these two pieces were made as a large creamer and sugar set but I've never seen them sell that way.
