Researching a pin

My cousin is researching this pin he has. Does anyone recognize it?

Awww my old signalman skills. That’s a Charlie flag for the letter C in the signal flag bag. It has stand alone meanings as well.

By itself- Affirmative
When followed buy numbers- Course in degrees

Been awhile had to look it up.
