An exceptionally fine and rare set of 12 English 18th century sterling silver teaspoons circa 1775-1785

The quality and condition of this rare set of 12 teaspoons is the best I have seen. They are feather edge engraved and have the original owner's initials in script on each handle. The spoons only have two hallmarks, one being he rampant lion and the other being the maker's initials T S.
