David, there's some useful information on 19thC portable darkrooms, with a couple of photos, in Michel Frizot's "A New History of Photography," which you may be able to get through your local library. Pages 119 and 158. There's even a drawing from 1863 of a bloke carrying his camera and darkroom on his back!
If you can't get hold of the book, let me know and I'll dig out my scanner and try to post the relevant pages to you. I'm new to APUG and haven't looked at how to post stuff, but I'll figure it out.
There's some good photos and info here:
and a few here:
