Gold Pocket Watch

by Harriet

I have a gold pocket watch that I’m trying to date. I’ve been able to identify the gold standard mark and the 18-carat sign but I'm struggling with the other two.

There is a shield with a cross in the middle and a person on either side, without knowing this I can't find the date: which is a gothic lower case ‘h’ in a rectangular shape with the corners rounded (if from London this makes it made in 1863 I think)… have been searching for ages but can't find anyone anywhere that has seen this hallmark before.

thanks:)
