This plume holder is used to secure a crest to some types of Roman helmets. The brass holder slides into its slot and the crest is put atop the fork-like prong. The crest then has its ends tied to the helmet to securely affix it into place. This holder can be used for front to back or side to side crests depending on the orientation of the slot on the helmet. This narrow fitting is intended to be used for the thinner, metal based crests.
