H e & co serving platter

I think this is very likely to be the Sheffield company Hawksworth, Eyre & Co. Your picture of the underside of this tray appears to show either discoloration or plating loss. To see which it is you should polish it with a good quality (non-abrasive) silver polish. If there is any plating loss it will be practically worthless. If the polishing brings up a nice shiny surface throughout then there will be some small value for display purposes.
