Can you help Identify fish knife

Hello, I have a pretty fish knife I’d like to identify, the hallmarks are not great but maybe someone recognizes the patterning. Thanks in advance for any help.

We need to see a picture. Although you mention the poor condition of the marks they would probably be of most use so please ensure that you include them in your picture/s. Take some care to get the image of the marks as clear as possible and don’t make the mistake of thinking that “bigger is better” - in-focus is best even if smaller.
