Can anyone help me identify this mark?

I’m new to this. I’m not sure what this mark means. Thanks in advance for all of your help.

It has an engraving that appears to be JF or WF on the handle.


LBSCo is Lawrence B Smith Co of Boston, Mass. As the mark includes the letters N-S I assume that the composition is nickel silver, a base metal alloy containing (bizarrely) no silver, rather than EPNS, electroplated nickel silver.


thank you so much. Can you shed any light on this marking on the same bowl

It’s a letter M, upside down, and is probably an owner’s initial.
