I like that one of them is holding a canister. The one on the right, notice that his saber belt is on backwards? looking at it closely, it appears there is a pistol butt sticking out on his right side - could be the reason the belt is on backwards, to hold the weight of the pistol. also, he does not appear to be carrying an artillery sabre. it looks more like a musicians or medical sword. As an artillery reenactor, I noticed the leather haversack on the man just behind the one with the canister. He would be the one to carry the round from the limber to the front of the gun (they would be placed in the leather haversack). In reenacting, it's hard enough to get our blank rounds out of the haversack we use. I always wondered how they did it with a complete round. I noticed that the one he has is quite a bit larger than the ones we use for reenacting (that are supposed to be the correct size)
