Hi Miles,
I can find nothing in my Scottish or Irish references, but a slim possibility may lie with Jean-Pierre du Port of Guernsey who used a similar mark but without the point at the base. Having said that, the reference that I found it in (Silver in the Channel Islands--Frederick Cohen & Nicholas du Quesne Bird) only has a distorted line drawing of the mark, perhaps taken from from an example of du Port's work.
du Port's working period was 1779-1788.
My scanner is not working at the moment, I'll try to take a photo of the mark tomorrow.
Trev.
