Hello everyone. This is my first post so please forgive me any mistakes and ignorance. I couldn't get my photos to upload so I posted url's to photos of the spoon and hallmarks. You will have to copy and paste one at a time into the address bar to view. The first 4 are of the hallmarks/makers mark. The last one is a picture of the spoon. It's a silver tea spoon.. Makers mark is R&D. The London assays crown mark is there. A Lion Passant although not sure which version. The date letter is R and based on what I can find online the shape of the outline corresponds to 1732 but I would be very surprised if that was the case but I am no expert so that's why I am asking you fine folks. Thanks in advance to anyone who replies!
R&D is Roberts & Dore Ltd, a London-based company, and the hallmark is Sheffield, 1959.
