As I have mentioned before there are supposedly two Oyster Servers the Oyster Server and the Fried Oyster Server. However, I could not find an example a plain "Oyster Server" only the Fried Oyster Servers. So here are examples of this serving piece. The pieces with the sharp pointed teeth are sometimes referred to as "Macaroni/Entree/Fried Oyster Serving Pieces". So, it is a bit confusing. After looking over all the examples (many more than are shown here) I feel the true Oyster Servers are the ones without the tines.
