The helm in the picture is unfamiliar to me. Is it based on a historical find? From this (admittedly poor quality) picture it almost appears to be a Vendel 1 helm that has had the cheek and neck guards from the Sutton Hoo helm added on. I don't recall any of the actual Vendel or Valsgarde helms having neck and cheek guards like this.
Does anyone have a better picture or more detailed information about this helm?
