Help with ID of Silver Fish Knife w Unknown Hallmarks

I’m hoping somebody could help with the hallmarks on this knife. I haven’t been able to match these to anything I’ve found online.

I’d be happy to send you the originals if that would be more clear.

Thank you for your time and help!

The letters shown are gothic style ‘EPNS’ - 'E’lectro-'P’lated 'N’ickel 'S’ilver.
The icon between the P & N is unknown to me, but I would suggest the knives are of the late Victorian/Edwardian era, and unfortunately not solid silver but plated.
