Asking people to prove that it didn't have the cannons is unrealistic. It is very hard, impossible in most cases, to prove a negative. What is a lot easier is to prove a positive. So it therefore falls to the "It had cannons" side to prove it. No evidence has been found to support that position yet, so go off and find it. I see some blithe statements such as chris3 saying "point 1, thay did!" Well, if it is that easy for you to know with the certainty of that statement, chris3, surely you can supply the data, no?
