Ron,

Are we changing the argument now?  And, is the tone getting a little
accusatory?

When you made the statement that you had observed rib crowning in an old
Knabe, I could have asked you the same questions, but I didn't think it
would be polite.  I'm going to try to keep being polite, 'cause if I've got
you upset now in my polite mode, you might have a coronary if I switched to
nasty.  I wouldn't want that on my conscience.
