Worn Hallmark on large silver spoon, help needed.

I’m having trouble identifying the hallmark on the spoon below. Hopefully someone here will recognise it.

I have a Jackson’s hallmark book but cannot see anything similar in there.

Your second image is the important one but it is too blurred to make out any detail. However I am pretty sure that it will turn out to be an electroplate mark as there is nothing which is recognisably a hallmark component. Here are a couple of links which might help:

Believe that’s a silverplate mark used by Briddon Brothers, Sheffield, England, 1863 - 1910.
