Assistance needed to identify hallmarks

Can you please assist me in identifying these hallmarks from a silver Claret Ewer. Two appear to be over-stamped

The first 3 letters are EPB so I am sure that the last one is M. EPBM is ElectroPlated Britannia Metal. So your claret jug is plated white metal. EPBM is a generic mark so it is not possible to say who the manaufacturer was.
