I have a small collection of bookmarks - hallmarked English, European silver, silver plate and either totally base metal or very worn silver plate. I have a couple which surprise me. They are both marked C&N with the word silver BUT I thought the C&N might be the maker's mark for Crisford & Norris, but would then have expected a lion, assay office mark and date mark. Can anyone identify the maker, material, country of origin or guess an age for this one? Thanks!!
