Montefortino - Coolus - Gallic

[Cremorn]

The Testudo De Bellis Civili range is designed for the Caesarian civil wars.
The legionaries come with montefortino, coolus, or gallic helm.

From AEIR I can tell what's a mortefortino and what's a gallic.

What's a coolus?

Thanks,
Richard.

The coolus was a round, bowl-shaped bronze-metal cap, to which could be added accessories such as a neck guard and/or reinforced "peaks" or ridges of medal and simple spike for plumes/crests. It came after the Montefortino, but before the Imperial Gallic, which was more specialized.
