Any help identifying this knife?

Hi all - I have this nice old bone handled knife. It is in the shape of a fish and the maker's mark seems to be Wilson. Does anyone have any info on age etc?
Many thanks

Houston Price lists a WILSON, HAWKSWORTH & MOSS in Sheffield mid nineteenth century.. Levine lists a WILTON, NY. (german imports) 1900. It sure looks old enough to be either. J.O'.
