Ruin of Doriath - Final Part

[Arvegil145]

I just remembered a late text (c. 1969) from the NoME that IMO implies that it was both the Dwarves of Nogrod and Belegost that took part in the attack on Doriath:

NB: the 'invention' ascribed to Dwarves by Elrond was of the invisible runes in moonletters only. All the same do not exaggerate Dwarvish linguistic ability. Though devised by the Sindar (owing to their enmity with the Dwarves of Nogrod and Belegost) it is probable (and was held true by the Noldor) that the idea of runes cut in stone etc. was derived ultimately from the Dwarves who had friendship with the sons of Fëanor.

The 'devised by Sindar' here refers to Cirth.
