Unknown sterling silver objects-Masonic items?

[Lilia]

I have four sterling silver triangles, with measured sides for about 2", heave gauge, nice patina, round holes at the top corner of each for hanging on a wire or other holder. There is a high relief center image at each of the triangle pieces: a sword, a book, a paper, and a key. I do not know the purpose/usage of these triangles, and have no evidence that they are masonic pieces. Does anyone know what these could be?

They would have been on neck ribbons, someone modified them by drilling the holes, the one with the attached loop would have been the origional style. They would represent: Sword=Steward, Book=Chaplain, Key=Gatekeeper, and Scroll=Lecturer. I believe they are from either a Masonic's or a Knights of Pythias' order jewels.

Thank you very much. It is very enlightening - I have exhausted my searches.
