SRI stainless New Pilgrim Japan flatware Stanley Roberts 4 pieces

Here are four pieces of stainless flatware. These are marked on the back, "SRI Stainless Steel Japan New Pilgrim." I think these are Stanley Roberts flatware. The handles are plain with a slight up tilt to the very end. There are small depressions along the middle portion of the handle along both edges. There is one dinner fork 5 1/4" long; one teaspoon 6 1/4" long; one sugar spoon 6" long and one butter knife 6 1/2"long. These are used pieces with normal household wear but no bends, dings or twists.
