Since we're deciphering code anyway... can I ask if anyone knows what this is?

It's not the Shrine or the regular masons, nor is it IooF. I don't think it's KoC either. I have seen that before, for some reason firefighter secret society comes to mind.
I'll have to look into this one.
Thanks! It might help to know that the pendant belonged to my great-grandmother (born in 1880's) and I didn't have any firefighters on that side of the family. Along that branch of the family tree, neither my grandmother nor my grandfather belonged to any secret societies either... wait, would Cosa Nostra be considered secret? (kidding... my great-grandmother was born in Ireland)
