Don Featherstone's Horse and Musket Rules - availability?

[Doug ex-em4]

I've an idea to play a celebratory Napoleonic game using Don's Horse and Musket rules. I have his "Wargames" book in which he mentions that the rules printed therein have been modified. So, my question is, does anyone know where the final version may be found?

Thanks

Doug
