It's a fish fork with a "C C" mark in which the mark was reversed somehow (don't know how since I thought the mark was like a hammer that get beat into the silver so how would that be reversed ? )
This is the apparently erroneous mark, the scale 'hangs' to the outside of the fork

This is the apparently correct mark (judging by the fact that there are more of them), the scale 'hangs' to the inside of the fork

Appreciate any insight
