Can this spoon hallmark and use of the spoon be identified?

I have a silver spoon that has been handed down in our family, I don’t know how many years. We were from north central pennsylvania.

There is a hallmark “CNS” on the spoon.

The spoon is an odd shape. Can anyone identify the hallmank and what the spoon was used for?

Thank you

Pete - its a cream ladle. I do not see that mark in my books. It is in the general style of American coin silver flatware pre-say 1860.
