Historical evidence for the use of light or blond horsehair on Roman helmets can be found, among other things, in finds of horsehair remnants on helmet holders and in ancient descriptions of the crista. This helmet crest with a metal frame is particularly authentic for the Weisenau type (Imperial Gallic), as this helmet type became the standard model for legionaries from the Augustan period onward and featured specific fittings for such crests. Combined with a suitable holder, the metal frame fits perfectly on the Imperial Gallic models (e.g., type G or H), which were often worn by non-commissioned officers such as the optio or centurion for identification purposes.
