Hello, how the Dude do I get this B B out?

I thought about taking the rings off then beating it with a hammer but I didn't want to mess anything up... Also, it's really rusty but could you believe I rode on this BB as it is all the way across S. C. in June. now that the cranks are off I can't even spin it by hand as it is so rusty. major change needed!

How to remove "flushed" BB? no teeth on cups??? perhaps is the correct question...

This is a Viscount & I'll need replace the bearings. Any idea how much this is or where to find such a part?

thanks!
