I have had another look at mark in daylight.
Looks letters K.C or H.C ,not petal as thought before.
Seems very difficult finding gold makers marks online.
Does anyone have any books with this info. (as I have said before ,it is amazing how many different books we need for research)
I have noticed on comments,some people also feel it is a French mark (18ct)
drawing of makers mark.
