You can get 25 ISO here: http://www.lumiere-shop.de/index.php...duct&info=1655 You can also get a 100 ISO version of the same film. The film originates from a company in the Balkans, and is cut to size in Germany.
I also use Ag Photographic. Matthew is extremely helpful, and I buy most of my film from him. However, they do not stock ULF format films at present.
Coincidentally, I am also in the UK.
Hope this helps?
