Dragon-helm of Dor-lómin
A visored steel helm, embossed and embellished with gold, that bore as its crest the head of Glaurung the Dragon. It was made originally for Azaghâl of Belegost, who gave it as a gift to Maedhros, who in turn passed it on to his cousin Fingon. When Fingon made Hador the Lord of Dor-lómin, he granted the Dragon-helm to the new lord, and indeed legend tells that only Hador and his son Galdor had the strength to bear the mighty helm.
There was at least one other Man strong enough the bear the helm: Galdor's grandson Túrin. He often wore the Dragon-helm to war, and took one of his many names from it: Gorthol, the Dread Helm. The last clear record of the Dragon-helm is at the Battle of Tumhalad, where Túrin is known to have worn it. Beyond this, there is a suggestion that he may have taken it with him to Brethil, and perhaps even worn it at the slaying of Glaurung himself. After that point, the great heirloom of the House of Hador is lost to history.
