Capital Q in a shield with a pointy bit in the middle looks like 1891. Capital F in a circle? I have forwarded on the image to a friend who gave me the book!
Thank you. Any idea what is ETR Q F Q and F seems to be a year, but together? As of ETR - it seems to be manufacture. Which one?
I think ETR must be the maker but a quick Google wasn't much help. Hopefully my friend will be able to help as he collects a lot of silverware
My contact confirms the above 1891 and the Edwin Thomas Bryant info and adds; The F in the circle cartouche indicates that it's foreign silver imported into the UK. The office of assay is London.
