Okay, here is the webpage I found the information about these wheels:

Apparently, they are "Nickey" wheels, not "Berger" as I previously stated.

I need a set of four for my Deora replica project. I emailed the advertiser on these ones...I've been told they are out of stock. No big surprise, as they were rare to begin with.
