Are these ice tongs or sugar tongs and who would be the maker?

The manufacturer is Currier & Roby of New York (see https://www.925-1000.com/americansilver_C3.html) and they are sugar tongs as ice tongs would have some sort of claw to grip the ice. These are commonly known as wishbone tongs as they have been made in the form of a chicken wishbone.
