Looking for Soren Berger Sphere Calipers

G'Day, would one of you kind folk have an Idea where a Yank could purchase a set of these Soren Berger Sphere Calipers, I tried his web site, but it's under construction, My understanding is the Gent is from New Zealand, but I thought perhaps some one may have seen some at a shop in Australia. No one in the US that I could find has them, and I'd even be willing to buy a used set.
Thanks
Ken
