Identify J.S 1868 makers mark

Hello all

I recently came into possession of a rather lovely Masonic jewel with a Birmingham hallmark for 1868 and a makers mark of J.S in a rectangle. My best guess is it was make by John Stone of Exeter but, apparently, he only registered this mark until his death which was in 1867. I didn’t know if the mark could have been held over on old stock?

Any help would be greatly appreciated.



This cannot be John Stone as his is an Exeter mark which would not be recognised by Birmingham Assay Office. Unfortunately there is no comprehensive reference for Birmingham makers’ marks, only partial selections. This J.S mark has not been publicly identified.
