When you do your book on camera recovering and repair let me know and I'll try to be first to buy a copy.

Well, I just figure that if you are going to do something, it behooves you to learn something about it.
Have you never had a vintage camera case with a surface that started crumbling when you began to clean it? Ever had one that, when you scrubbed it with a toothbrush, the toothbrush ate into it? If so, that's probably what it was. Used to tear up whole libraries of leatherbound books and nobody knew why. They blamed it on gaslighting, which was only half the problem. The other half was atmospheric pollutants, due to the widespread burning of coal (specifically sulphuric acid). http://calisto.slv.vic.gov.au/latrobejournal/issue/latrobe-73/t1-g-t10.html

Make that....very dry vegetable tanned leather.
Yep, stiff and dry. It can be brittle too.
