Go to http://www.rotordoc.com, and look under "Bell Rotor History"
It's got much information.

Hi gang,
What's the difference between a Ham IV and a Ham M? I thought that the Ham
M didn't have the wedge brake assembly and so was a little shorter but
otherwise they were the same.
I just bought a Ham M off eBay and got it today. It looks just like my Ham
IV or at least what I thought was a Ham IV.
What's the difference and how can I tell?
