Help to identify maker of these 925 silver badges

[Saint_Christophe]

Hi forum! Once again a nice lot of Saint Christopher dashboard badges. They are all marked 925 with a mysterious mark to me. Any idea?

Thanks in advance!

Thanks anyway… good idea to mirror the hallmark to see if someone can identify it this way!
