The Sutton Hoo example shares similarities in design, yet "is richer and of higher quality" than its Scandinavian analogues; its differences may reflect its manufacture for someone of higher social status, or its closer temporal proximity to the antecedent Roman helmets. Anglo-Saxon Although the Staffordshire helmet, currently undergoing research and reconstruction, may prove to be more closely related, the four other known Anglo-Saxon helmets share only minor details in decoration and few similarities in construction with the example from Sutton Hoo. In construction its cheek guards and crest link it to its Anglo-Saxon contemporaries, yet it remains the only helmet to have a face mask, fixed neck guard, or cap raised from a single piece of metal. Decoratively it is linked by its elaborate eyebrows, boar motifs, and wire inlays, but is unparalleled in its extensive ornamentation and pressblech patterns. The similarities likely reflect "a set of traditional decorative motifs which are more or less stable over a long period of time"; the differences may simply highlight the disparity between royal and patrician helmets, or may indicate that the Sutton Hoo helmet was more a product of its Roman progenitors than its Anglo-Saxon counterparts. The primary structural similarity between the Sutton Hoo and other Anglo-Saxon helmets lies in the presence of cheek guards, a feature shared by the Coppergate, Wollaston and Staffordshire helmets, yet generally missing from their Scandinavian counterparts. The construction of the Sutton Hoo helmet is otherwise largely distinguished from all other Anglo-Saxon examples. Its cap is unique in having been raised from a single piece of iron. The caps of the other helmets were each composed of at least eight pieces. On the iron Coppergate, Shorwell and Wollaston helmets, a brow band was joined by a nose-to-nape band, two lateral bands, and four infill plates, while the Benty Grange helmet was constructed from both iron and horn. A brow band was joined both by nose-to-nape and ear-to-ear bands and by four strips subdividing the resultant quadrants into eighths. Eight pieces of horn infilled the eight open spaces, with the eight joins each covered by an additional strip of horn. The Sutton Hoo helmet is the only known Anglo-Saxon helmet to have either a face mark or a fixed neck guard; the Coppergate and Benty Grange helmets, the only others to have any surviving form of neck protection, used camail and horn, respectively, and together with the Wollaston
