A paragraph from a larger article that explains the 'WB' marking on the item:
Having foresight commensurate with his ambition, Robert Wallace, with his sons, Robert B. and William J., reserved the right to make, on their own account, forks, spoons and other flatware of any other metals than nickel silver. Mr. Wallace then began to make sterling table silver in addition to the nickel silver (which by the way he was now equipped to electroplate), and three or four years later he went to the other extreme and brought out a line of steel spoons and forks, commonly spoken of in the trade as “tin,” because they are plated with this material. This latter line was brought out by a separate company known as Wallace Brothers, and composed of his sons, Robert B., William J., Henry L., George M., and Frank A., and two sons-in-law, W. J. Leavenworth and D. E. Morris. (This company was later merged into R. Wallace & Sons Mfg. Co.) The bringing out of these two new lines illustrates well the ambition, the practicality, and the mechanical genius of the man. He wanted lines to sell to all classes of people; sterling to the wealthy, plate to the multitude, and “tin” for cheaper trade; and he was mechanically versatile enough to produce good products in all three of these classes of material.

The timeline of the above snippet is c.1875. I would assume that the term 'Stainless' referred to the tinning of the steel, rather than that of 'Stainless Steel', a later development. Perhaps the trade mark was in use years before it was officially registered.
