The Aux. Infantory 'B' made by Deepeeka is an accurate replica ornate based off historical research and authentic in its design. This helmet was a type of ancient Roman helmet. It was produced from brass and, like the Montefortino type with which it co-existed, was a descendent of Celtic helmet types. It was fairly plain, except for some ridges or raised panels on the cheekpieces. It was globular or hemispherical in shape (some were spun on a lathe rather than hammered to shape) with a turned or cast crest knob. The Coolus was replaced by the Imperial helmet type, a more developed form also derived from a Celtic original. Our version has a simple design lacking a crest mount. It is fully functional and made from brass. Internal circumference is 22-23 inches. This incredible helmet is great for your next Ren Fair, role-playing performance or to simply add to your collection!
