This is a matching set with only the suneate missing of a suit of armor from the Japanese clan Hosokawa family, worn by them or their retainers. Although this type might later be adopted by other families. The creating of the basic model goes back to Hosokawa Sansai (or Tadaoki, 1563-1646). It does require a "touch up", but is in otherwise fantastic condition. 

The helmet is an Etchu zunari-kabuto with it's distinctive shape typical for the Hosokawa clan. As well the hanpo, an Etchu-bo fits with this. It is a Yokohagi nimai-do, a two part culrass in which the lamellae are arranged horizontially, with the armor plating made of hardened leather (nerikawa) except the side plates, under the armpits (waklita) and the respective upper plates (munaita/oshitsuke no ita), which are made of iron and a light leather. The lacing is leather (here, e-gawa) and shows two different patterns, which may be a later restoration. On the shoulder bridges (watagami) an unarmored collar (eri-mawashi) attached in which the same carrier fabric (leji) as on the "nigu" was used.The hanpo, an Etchu-bo fits with this. Attached to this type of zunari-kabuto is usually a shikoro without fukigaeshi, at which the lames are covered in thin leather. Additionally is the lowermost lame edged with a narrow leather band (kawa-fukurin). The sangu consists of sleeves (kote), thigh protection (haidate) and shin protection (suneate) which is missing in the set. The suit is trimmed with ue-kuma-ge (kuma=bear) and is on the kusazuri. Which might have been considered "macho".  All parts have the same basic fabric (leji) and thus form an original set that belongs together.
