Is this rib seperating?

[King Cobb]

Pardon my ignorance on this, but I have yet to encounter a rib separation other than when they are obviously pronounced.

My question is regarding this trojan an old farmer showed me today when we were looking at his wheat crop.

Are these barrels separating or is it just age? I don't have any parkers that have a similar look on their ribs so I was just curious.

He was asking me what I might give him for it. The wood is in really good shape, action is grey but not bad but the barrels need some help regarding the bluing and whatever issue this might be.

Thanks as always.
