I love Clint Eastwood in the Leone films (Outlaw Josey Wales was good, but I have to admit I prefer the fake, stylized Man with No Name trilogy, scored by Morricone!) but the best Western hero in existence is Toshiro Mifune in Yojimbo!
I'm interested in what that small caliber cannon is, about the 10th picture in...it looks more like a WWII antitank gun!
Wait...wait a sec...is it a trailer of some kind and what I'm thinking the barrel is a hitch? If that is the case the "lid" of the box appeared like armor plating. Seriously, what is that?
EDIT: OK, I need to look closer, that's obviously not a gun, its a trailer with a chest for supplies or whatnot. I was thinking they were preparing for Union Pzkpfw IV Ausf F's coming over the ridge or something!
