My grandfather recently gave me this mug that has been in my family for a few generations. I have done some research, but can't seem to find an identity for the Maker's Mark. I believe it is from London, and I think made in 1761 (but I am really unsure of the Date letter identification F?). Any help would be great. The closest thing I came up with was Fuller White, but I could not find an example of his mark.
