According to the book If you disagree your argument is with the authors not me.

Well, its great if you have the book in front of you in it, i was doing it from from looking at a photo with no book telling me exactly what it was.:diablo:

As far as i`m aware there has been no argument, mike currill just wanted to know how i came about my guess. Which is all it was, an educated guess.

I thank you.
