Thanks Mr Wildcat for sharing the above links to the sites. I find Ed Moormans site extremely informative, especially for helping people in a forum such as this.
I am glad to see the method I mentioned above (actually its the way George Aldrich taught me) is very similar to Ed's.
Again, outstanding sites, thank you for sharing.

I too have the understanding that the Rossi's are ABC, educate me on where you find the info of them being ABN, I sure would like to know.
