Re: Dragon-Helm

Here is the whole passage of UT:

It may be noted here that it was my father's intention to extend the history of the Dragon-helm of Dor-lómin into the period of Túrin's sojourn in Nargothrond and even beyond; but this was never incorporated into the narratives. In the existing versions the Helm disappears with the end of Dor-Cúarthol, in the destruction of the outlaws' stronghold on Amon Rûdh; but in some way it was to reappear in Túrin's possession at Nargothrond. It could only have come there if it had been taken by the Orcs that carried Túrin off to Angband; but its recovery from them at the time of Túrin's rescue by Beleg and Gwindor would have required some development of the narrative at that point.
An isolated scrap of writing tells that in Nargothrond Túrin would not wear the Helm again "lest it reveal him", but that he wore it when he went to the Battle of Tumhalad

(cf The Silmarillion p.212, where he is said to have worn the Dwarf-mask that he found in the armouries of Nargothrond).

note continues:

For fear of that helm all foes avoided him, and thus it was that he came off unhurt from that deadly field. It was thus that he came back to Nargothrond wearing the Dragon-helm, and Glaurung, desiring to rid Túrin of its aid and protection (since he himself feared it), taunted him, saying that surely Túrin claimed to be his vassal and retainer, since he bore his master's likeness on the crest of his helm.
But Túrin answered: "Thou liest, and knowest it. For this image was made in scorn of thee; and while there one to bear it doubt shall ever assail thee, lest the bearer deal thee thy doom."
"Then it must await a master of another name," said Glaurung; "for Túrin son of Húrin I do not fear. Otherwise is it. For he has not the hardihood to look me in the face, openly."
And indeed so great was the terror of the Dragon that Túrin dared not look straight upon his eye, but had kept the visor of his helmet down, shielding his face, and in his parley had looked no higher than Glaurung's feet. But being thus taunted, in pride and rashness he thrust up the visor and looked Glaurung in the eye.

In another place there is a note that it was when Morwen heard in Doriath of the appearance of the Dragon-helm at the Battle of Tumhalad that she knew that the tale was true that the Mormegil was indeed Túrin her son.

Finally, there is a suggestion that Túrin was to wear the Helm when he slew Glaurung, and would taunt the Dragon at his death with his words at Nargothrond about "a master of another name"; but there is no indication of how the narrative was to be managed to bring this about.
