I have a set of 6 small porringers...maybe salt cellers, they measure 2 inchs across not counting the handle which has 4 heart cutouts. The bottom says L. B. Smith Co. and under the touchmarks says Boston. The touchmarks: First is a fleur de lis, then two other symbols I am not sure of. The metal does not look pewter but may be silver...has a nickel or coin smell to them. I cannot locate anything on these. They are old and go back several generations. Do you know any thing about L B Smith Co in Boston?
I suspect your items are salts in the shape of Porringers manufactured by Lawrence B. Smith Co. The company was founded in 1887 and went out of business by 1958. They made both sterling and silver plated items at 326 A Street in Boston.
Since they are not marked STERLING I suspect they are plated.
