O.K. So I am going to put my intelligence on the line and say something that may be obvious. But the horse displaying the cannon is fake...right? I mean...like the tail...it just doesn't look right and the horse seems to be a able to "strike a pose" and hold it. And it looks like some loose grass strewn about its feet to possibly hide some support for the whole giddy-up.

Check out this Rock Island Arsenal horse "mannequin". You will have to scroll down some.
