Does anybody know how to disassemble a medical oxygen tank?

I have a small one that's empty and needs to be disassembled.

Thanks,
Dan.

Are you making something cool with it? I have access to a couple of them, but couldn't come up with something to do with them.

I want to make it into a small air reservoir for my ARB, reducing the amount of times my compressor cycles.
