Draugluin the werewolf wrote: the black armour is generally thought of as galvorn

Indeed, this assumption is well placed. As it is also stated in the text, that following the death of Ëol, Maeglin instructed the folk of Gondolin, in a form of the craft of Galvorn.

The extract above probably refers to the Elves under the command of Maeglin, that used some form of the armour. Although adding further armour is fantastic, we can assume that the currently implemented Galvorn is close enough, to what you have described.
