That looks like a really old tin with some storage problems with the rust on the sides. The Kodalith I have are in 100ft rolls, encased in a black plastic box. Ive got about 250ft or so left. It is very interesting stuff, that I just havent had enough time to really play with.
Like others have said, it is very high contrast, and low speed. You can handle it under red safelight, and develop by inspection. I have also developed it for continuous tone in very dilute rodinal with semi-stand development. It is extremely fine grained.
Here is a scan of a test shot I developed in continuous tone.
Things you can potentially do with it: the high contrast negs are good for sabattier printing, you can contact print very high contrast copies of negatives you already had for interesting effects with it as you can handle it under red safelight, use it to shoot objects you would want to make stencils or other graphic art projects with, using it in urban areas to erase moving objects, such a people from scenes, you can use the low speed as well to shoot wide open in bright light without ND filters.
