This is the mark on an Old English pattern tea spoon. It is difficult to see from the pictures, but there is a rubbed mark on the left which I can just make out to be a capital “B”. There is an “H” then a maker’s mark and then what appears to be an “R”.
The maker’s mark seems to be “M• ?”. I have seen similar marks attributed to Banff makers, but I cannot find any mark which corresponds to this one in any references of Scottish Provincial marks.
I am sorry that the pictures are not clearer. I have tried to enhance them as much as possible.
