This listing is for two Teaspoons for the Kensington/International Silver pattern INS258.  I do not know the age of the pattern.  The spoons measure about 6 inches long.  One spoon shows a lot of wear on both sides of the bowl and the front of the handle.  The other spoon has a lot of plate loss on the back of the bowl and a couple of dark spots on the back edge of the handle.  They are marked Kensington Silver Plate on the back of the handle.  I will gladly combine shipping.  Please e-mail any questions.
