[LargeFormat] Bag Bellows Material

[Tim Atherton]

The stuff Toyo uses on the 45A etc is synthetic but is good in cold. I think
Gandolfi now uses the same stuff and Universal Bellows uses it in the UK -
if it's the same stuff as Toyo.

Anyway - it's supposed to be good to -30c - I've used it to -40c and it
hasn't stiffened or cracked. (my film did though....)  - don't imagine it
gets that cold in Bristol...
