Name stamps occasionally appear on early Roman Period bow brooches, such as Aucissa brooches, Nertomarus brooches, brooches with side knobs (Scharnierflügelfibeln), and rosette brooches (Kragenfibeln, Distelfibeln, Flache Distelfibeln). Aucissa brooches are known from the territory of the whole Roman Empire and were produced in multiple workshops, while the other types were typical of the western parts, having been manufactured primarily in the western provinces. According to current research, the 55 bow brooches from Győr-Ménfőcsanak-Széles-földek belong to different western types. The only stamped brooch is a fragmentary Nertomarus brooch with an abbreviated NERTOMARVS stamp (NORV). This brooch could reach Pannonia from the place of production in different ways. One option is that the brooch travelled with its owner, a military person, or someone who accompanied the troops.
