I am surely glad that you gave us that geology lesson. From what I remembered of my Geology class taken about 40 years ago, most everything south of where the Ohio runs into the Mississippi River is a product of a Marine( shallow sea) environment, and of course, wind and water born sediments. Not exactly where any geologist would be looking for Aluminum, or Bauxite ore. I didn't know the total geology of the Ozark Mountain uplift, so you have filled in that gap, now, for me. Thanks.
I have always suspected the Musso Bowie as an old fake, simply because it is so unbalanced and clumsy, like a cleaver with an attitude! That brass piece on top never felt right, because it can't do the job Musso claimed it was to do- catch and turn or break oponent's blades. Brass is just too soft, and the wrap too thin.
I have to wonder if most people who claim to " Know " that his is the true Bowie knife design, have ever tried to sink a blade's edge into any piece of brass far enough that the brass catches and holds the blade strong enough to break it, or twist the blade out of your hand? I tried it with an axe, and couldn't get the blade into the brass far enough to do this. I can't imagine being able to do this with a knife, or sword blade.
And, as I have already mentioned, the blade is very clumsy to be moving in any kind of slashing motion, either to parry a blow or to deliver a serious wound to an opponent in a fight. I have no doubt that the weight is sufficient to do serious damage if that blade contact flesh and bone, but I can't see a knife fighter choosing this design for his life-saving knife in close quarter combat.
Finally, with the sharp sweep upward of that false edge, even a stabbing motion with this knife would be sure to be limited in depth of penetration by that false edge. The musso blade looks like a cleaver, with a pointed edge added to it, a fancy hilt, or guard, and that silly piece of brass added to the backstrap.
By comparison, the Moore Bowie at least has narrow cuts in the backstrap of the iron blade, and those cuts have the potention of catching the edges of some knives, so that the blade might be broken, or the opponent's knife wrenched from his hands. I am thinking of a thin bladed knife like a dagger or dirk in the hands of an opponent, or even a thin bladed carving knife. I am not convinced, however, that the Moore Bowie is the real deal, either. It is probably an early copy, as so many copies were made and sold world wide, after the fall of the Alamo, in 1836.
