Here are some examples of Long Handled Sherbert Spoons. Looking back on my earlier post on Sherbert Spoons, I see that these are not any longer than those, however the bowls are smaller and not as fat, giving the stems a longer profile. Just my guess as to why these (of the same length) are referred to "long".
King William was first introduced by Tiffany as a pattern named Antique in 1870. Later the name was changed to King William. It is as simple a design as a pattern can get. Fork (8 1/2 inches)
Unlike the previous patterns by the same name, Towle's Hampton is more ornate. It was introduced in 1892. The stem and terminal are decorated with a design of scroll work. Fork (7 1/2 inches)
