1674 London Trefid Spoon Maker's Hallmark Unknown

Am wondering if anyone can help to identify the maker of this London-marked, 1674-dated trefid spoon, please?

It weighs a very respectable 60g and is 20cms in length.

Many thanks if you have any ideas!

Robert King. See Jackson p131. Mitchell attributes it to “probably Robert King”.


Brilliant! Many thanks, Phil! Much appreciated!
