As I mentioned in my earlier post on Chipped Beef Forks, they come in three sizes: Small, Medium, and Large. And, often patterns will have some combination of the three sizes. Here are some more examples.
Georgian by Towle ( Small 6 3/8 inches)
Old Newbury by Towle (Large 7 1/8 inches)
Old Newbury by Towle (Small 5 7/8 inches)
Note difference in design between the two sizes
Lily by Whiting (Small 5 3/4 inches)
Fairfax by Durgin (Medium 6 inches)
