Bertha Butt
According to either The House of Krupp, or The Arms of Krupp (I can't remember which, it's been a while), Big Berthas where more like squat, large caliber howitzers, but the Paris guns(yes, gus, there where more than one) where called "Long Max". No Man's Land by John Toland has more details about the number and location of the Paris guns.
