What fork Is this?

My friend, Anne, sent me this image of three forks from an old set she got from her mother-in-law. They are Christofle European silver, but she is unsure of a pattern. Christofle is rather notorious for their multitude of fork designs. My best guess:

Cake Fork -- I saw one in a different pattern with the wide cutting tine and another single tine, but a two tined cake fork???

Small Fish Server -- Again, I saw a set of Christofle that had an entire drawer of "fish eating" implements with several four tined servers, but fish servers are usually more ornate. Maybe this is the Fish Offering Fork?

Shellfish Fork -- I think this has all the points of a generic shellfish fork.

Christofle mentions as some of its forks including a Fish Fork, Salad Fork, Two Pronged Fork, Cake Fork, Oyster Fork, Huge Helping Fork, Salad Serving Fork, Fish Offering Fork, Fruit Fork, Cold Meat Fork, Baked Potato Fork and Carving Fork, just to name a few....

I know someone out there knows the truth.
