BC,
There are a couple of variants of the RAR Band's over-sized badge for the Glengarry. Vol2 (@CB 323) shows the badge (fronts and backs) in chrome and gold plated versions of both the counter-struck and the (later) spin cast variants.
Having said that, the recent image I posted here and on FaceBlab
etc, is apparently a white metal counter-struck version, which looks like it has a protective lacquer coating... so that in angled light, it actually looks to be a plale gold colour.
I hope that helps?
Regards
Mark
