These are some examples of flatware pieces from the British side of our family. We have others which have an “EP” marked on them, so I am assuming those are plated.
The two pieces in the upper section of the picture are light in color with no tarnishing. The one on the bottom is tarnished - maybe more likely to be silver, but no sterling label on it. Looks like the letters on the bottom one read “E&Co.”
Any help you can give would be appreciated.
