Hi, Looking for a little expertise here... please
I purchased this recently at an estate auction in the US - I cannot find any reference to N pellet H in any makes mark around 1750 for London. The shape & size is right so I don't think it is a fake. The "tree" marks looks a bit like an Inverness mark and the britecut work to the back seems unusual. Also the maker's mark itself appears quite crude. Is it possible that this is a "colonial" mote spoon or, even more unlikely, really a Scottish provincial spoon made in Inverness!
Here are two pics
