Here is a Cocktail Seafood Fork the for the Oneida pattern Croydon.  I do not know the age of the pattern.  The fork is in very good condition.  It measures about 6 inches long.  It has a nice shine.  I do not see any plate loss on the back heel.  I will have another piece of this pattern listed.  I will gladly combine shipping.  Please e-mail any questions.
