"Viking" yeast

I am curios if anyone knows where to get hold of a type of multi strain 
S. cerevisiae.
This type of yeast was given to Keith Thomas, a brewing scientist at the 
University of Sunderland by Michael Jackson who got that sample of yeast 
from a traditional brewer in Voss, Norway. The Yeast was handed down by 
generations of brewers, and is perhaps the oldest known type of European 
ale yeast. It has  different taste characteristics then "modern" S. 
Cerevisiae.

I have tried to email Brewlab Ltd at University of Sunderland but no 
reply to my enquiry.
