Here we have, what is to me, a mystery. A feather edge tablespoon with a shell bowl, with a quite normal set of marks indicting that it was made by Thomas Chawner and assayed at London in 1774. It measures nearly 8¾ inches (22cm) in length and weighs 75gms.


However, the spoon also is stamped with an additional set of marks.


RB - Tudor rose - Hibernia - Lion Passant
It's difficult to be sure which set of marks were stuck first, the mystery set are far more worn, but were probably struck lighter than Chawners. The English marks are in a position that you would expect for 1774, but the position of the others may be quite normal depending on their origin.
I presume we are looking at a colonial set of marks. Does anybody recognize them?
All thoughts appreciated.
