Hi.
You have an idea of ​​what a hallmarks it is ?
Regards

I think that's the English Exeter Town mark and Georgian duty mark. There should be a date letter and makers mark somewhere but its a small piece so it's not totally unusual to not have all the marks.

hi legrandmogol
Thank you, maybe this is it.
Does anyone have any idea yet?
Regards
