South Wales Borderers Collars - Are they?

[Faugh-A-Ballagh]

I have had these for way over 20 years, and in my complete ignorance thought they were from a Royal Anglian Regiment battalion as they were rather like the Lincolnshire Regiment badge. However, after seeing the clip from Zulu in the programme about the Royal Welsh on telly recently, I suddenly remembered that they may have been bought at the South Wales Borderers museum as a present.
I really hadn't ever given them a lot of thought, but after a bit of a shine, I thought I should really do something about them.

Again, apologies for lack of knowledge. Glad they did away with guru status. I would never have felt comfortable with it!
