Mixed piece metal, colonial, serving set, not marked except small piece

This is a nice set of pieces that would look great in a home that decorates with a colonial or traditional style. These pieces are not totally an original set, but were gathered together and make a nice looking set. They are cast and the line of the casting is evidence on some pieces. They are not magnetic. I am not sure if there is pewter or if this is a very heavy cast aluminum. But visually it gives a pewter look for decor. The small piece does say USA and has a stamping of a circle with a large W with an R on one side and a P on the other side. this piece could be more special. Lovely heavyset. There is one tiny chip on the edge of the bowl. Please message any questions.
