I recently acquired two small dessert looking dishes. They are both stamped on the bottom with: Victor S. Co.; E.P.-N.S.; silver soldered; R0107; 4 oz. then the number 55 in a box. All of these lines are one beneath the other, except for the last, 4 oz. and the 55 in a box, which are on the same line. Does anyone have any ideas about these? Thanks for the help.
