The exact origin of mail is not known, but the earliest examples were found to be made in the 4th century BC. One of the earliest discoveries is the mail from the Hjortspring swamp in todays Denmark. In the 12th and 13th century it developed to the most important piece of armour in Europe. This chain mail is made for men with a medium chest circumference. It is wide enough to be worn on top of a gambesons. It is made with long sleeves and reaches down to, approximately, the knees. The blank chainmail is finished in shiny zinc; the rings are treated electro-chemically, and therefore need a little less treatment, than untreated models. The oil finished one needs more care, we suggest to use Ballistol machine oil on a regular basis for treatment.
