Can’t read the marks, but the spoon is by the Whiting Manufacturing Company, originally of Massachusetts. From 1880, they produced flatware with a series of different ‘Berry’ designs, and this one was known as ‘Blueberry’ pattern. By this time they had transferred production to New York (692-694 Broadway at Fourth Street), the original factory having been destroyed in a fire.
Whiting did not introduce date marks on their pieces until 1905, so if it has no date symbol, it will be sometime between 1880 and 1904.
