Leica and equipment ID

[boristheblade]

I'm new to film photography, so please take it easy - I know I'm extremely clueless :dunno:. I recently acquired a Leica M2, and these pieces came with it. Any idea on what the following items are? Also, what is the machine called that is used to agitate the chemicals used in the dark room by swaying the tub back and forth?

Thanks a bunch!

Second picture is called a Visoflex, and it appears to come with bellows. It is used to convert a rangefinder into an SLR to do macro photography. You may wish to google "Visoflex" to see other pictures of the same thing.
