Hi folks, first post here so may need some guidance...
My grandfather ran a metal-plating business and worked with a designer. He registered a hallmark, which as far as I remember incorporated his initials as well those of his colleague, in the form of a quadrant. His name was Lewis Tuck and the designer's, I think was George Ransome, so the four letters were L, T, G & R. I haven't seen the hallmark in decades and am simply going from memory - can anyone advise me on how or where to look it up and find out about more about this part of my family heritage?
