Harmonic Dampener questions

Congrats on using the correct nomenclature, a dampener, not a balancer.

Made in Oz, it is probably a Power Bond, made in Wagga, NSW.
Even though I live in Oz, I cannot buy this here, I have to buy from the US. And the shipping cost.....

And you were wondering what was wrong with the world today.....
Looks to me like both brands are available in Oz.
I think Powerbond used to put a steel ring on the stock damper hub. I seem to remember them doing one or two for me ages ago like that.
I haven't checked in a while, but they probably still do.
