Please could you help me to identify the hallmarks on this silver half oystershell dish. I am not sure if it is silver or silver plate and I do not know its age. I think the hallmarks show (from L to R) : G (very faint), E, H, lion passant and a crown.Any info would be much appreciated

Many Thanks for your help. I enclose a link to an excellent book on old english hallmarks which i recently found on the internet [I think it is in the Kansas City library) [Old Silver And Old Sheffield Plate : Howard Pitcher Okie : Free Download, Borrow, and Streaming : Internet Archive](Old Silver And Old Sheffield Plate : Howard Pitcher Okie : Free Download, Borrow, and Streaming : Internet Archive)
