Perth Regiment Cap Badge questions

[pduskocy]

I wonder if someone can help me learn more about this cap badge and these buttons. Admittedly, until yesterday when I discovered them in a jar of old buttons that I bought at a garage sale, I had no idea what the badge was. I’ve read every post on this site about The Perth Regiment but haven’t seen a reference to this type of badge. From the perthregiment.org website I’ve learned that it may be what’s called a 1st pattern cap badge. I’d really like to get an idea of their age, value and any other information known about them.

Thanks for your time!
