Oneida Community berry spoon marks

[green-eyed1]

Hi! Sorry no photo. Have an old berrry? spoon with following marks ~
S in a diamond, S in a sheild, then a P in a square. Any help would be appreciated.

Without seeing any photos, your description sounds like the marks of silverplated flatware made for Sears Roebuck and Co, Chicago, Illinois, by various companies and sold, in this case, as Salem Silver Plate (first used in 1914.)
