Thanks. How about the East European manufacturers? Anything on www.fotoimpex.de? If there's a 110 B&W film to be had, I'd bet that's where you would find it.

I remember long ago shooting Verichrome Pan in 110, processing it on a stainless steel reel, and enlarging it onto Velox with this dreadful plastic enlarger I got when I was about 10 years old. I may still have a roll or two of those old negs in the the files.
