Another typical post needing help on a hallmark I can not figure out. It looks like it is a TS&S then a bird of some sort and EP (electric plated?). I appreciate any help on this one.
Yes, EP is electroplated so, strictly speaking, the mark is a trade mark, not a hallmark. There is no comprehensive reference for electroplaters' marks and this one seems to have escaped any sort of listing so TS&S may have to remain anonymous.
