I've had some images sent to me of a unusual (to me) item:







Can anyone suggest the purpose of this piece? It would appear to fish related, perhaps for filleting at the table?
Also, any thoughts on the maker would be appreciated, the marks are tiny and these were the best images that could be obtained. It's 'H & C', but the symbols are not clear, but maybe those of Hauvy Fils & Crampon of Paris?
All thoughts very welcome.
Trev.
