I've expanded French Movie-Makers question about getting a Super-8 developing tank. Perhaps links about developing your own Super-8 film will lead to where to get the supplies.
This link might do the trick.

It looks like the website in general may have good info on all aspects of Black and White developing.
This is just a starter link. Any other suggestions are welcomed.
