Barrel helm

From MiddleWiki

A helm common in the 13th and 14th centuries, featuring a flat or slightly rounded oval top plate riveted onto an oval canister of steel with a narrow eye-slit, or ocularia, in front, and breathing-holes drilled into the faceplate. The barrel helm is popular in the SCA, as it provides excellent protection, though with less useful glancing properties than the bascinet. This may be partly because barrel helms can be properly constructed even by those with limited metal-working experience, and because excellent patterns are in common circulation in SCA publications, courtesy of the Middle Kingdom's Sir Polidor Haraldsson.
