I have for sale today a good example of a vintage Scottish Holy Royal Arch(Chapter)Companions Breast Jewel..Made of a yellow colour metal,with  nice crisp detail.Has been worn so expect normal wear associated with this..Fixing pin is present and intact at the rear..The ribbon can obviously be changed according to rank.May benefit from a clean but can certainly be worn as it is.Rear is blank so could be engraved for presentation.
