Hi,
The maker is Richard Hodd & Son of London.
There is no date letter, the mark (pictured upside down) is a Fleur-de-lys, the letters 'E' and 'P' (Electro Plate) and a Crown.
Their business can be traced back to 1849 (Goodfellow, Tilley & Hodd) and I believe they are still in business today.
The use of a Crown in their mark would indicate a date of pre 1897.
