They are Breyton Avalanches but from what i have heard they dont make them anymore. They were made by ATP in Italy but sold as Breyton. They have also been sold as other brands such as Oettinger, Projectzwo, and OSIR so not sure if ATP sold the rights for them to the other brands.
I have had the rims since 2001 originally on my A3T and cost me a mint. The reason why i love them is that they are deep dished and a timeless design so still looking stylish 8 years later!
You can still buy them from Germany as you can see below:
