Can anyone help me understand the hallmarks and date of this please?
Your pictures are not good enough to be able to help you fully. To photograph silver you should use natural light and not get too close so that any marks are in focus. In addition there should be a full set of marks on the body of the caddy. I believe that the marks you have shown comprise a partial maker’s mark, lion passant for sterling silver and either the uncrowned leopard’s head of London or a Victoria duty mark, but there is not enough definition to be sure of the latter. Have a good look for the full hallmarks and have another go at getting some clear, in-focus pictures.
