I recently acquired a pair of (or so I was told) post-WWII cuff links that were handed out to surviving RAF pilots. I am no expert or collector, and I am also not sure of the authenticity of them, but I would love if someone who was more informed could tell me a bit more about them. The box contains matching cuff links, and a pin that has the same insignia but is considerably smaller. I will attach a photo that shows them.

Also of note, the back of the links has the words "stones melb" indented into it, not sure if that is of any significance.
