I came accross these very fancy hollow ware/flatware knives and forks. Engraved blades and tines, very ornate. Handles are light and feel hollow. I believe they are British but am not sure.
The first hallmark looks like a lower case "r" or a hatchet. Then HBS and a Crown with EP below, which I believe was not allowed in Britian after 1885.


As always, much gratitude for your expertise!
