This is a 60 Piece Stieff Sterling silver complete set including:

8 Dinner knives, 9 inches long

8 Dinner forks, 7 inches long

8 Salad Forks, 6 inches long

16 Teaspoons, 5-5/8 inches long

8 Soup Spoons, 5.5 inches long

8 Butter knives, 6 inches long

4 Serving spoons, 7-3/4 inches long

It weighs in at 2,456 grams.  The knives by themselves weigh 583 grams, and the handles are hollow.

Very nice set, these were my great aunt Ruth Holman Wilson's, she was born around 1908.  The 16 spoons are all in the same cloth bag, the rest of the Flatware has their own blue cloth bags.
