I have heard these refered to many times as the beginnings of the clansman buckle and strap in scottish heraldry but I can not seem to find any in existance. Supposedly a chief would give a silver plate medallion that bore his crest to his retainers. This was to be held around the neck by a leather buckle and strap. When it was not in use it was stored flat with the buckle and strap surrounding the crest. Thus was the beginning of the clansman's crest badge.

Does anyone have any images of such a thing. Below is the only one I have ever seen.
