My Father In-Law had these knives..Help please!

I don’t know much about these as my father-in-law has passed away. My mother-in-law knows nothing about it. I do know what the HH stands for (Hollow Handle) but can’t find what the other marking are.

The knives are part of a fish-eater set and are either electroplated or a base metal alloy. The manufacturer’s mark on the blade is HB&H which are the initials of Harrison Brothers & Howson, a Sheffield company. HH is actually just another mark of Harrison Brothers & Howson.

Thank you, Phil, so much for that information.
