Savage-
Those are the four racks from the hanging hogs in the earlier photo
Her hog was intact due to her ear-shot. Both racks were whole. Mine had bullet damage that messed up two ribs going in and another two on the exit side. Added to two racks of store-ribs put in by my neighbor...in his wet-smoker, we had 6 large racks for a Sunday picnic lunch. He works for Brown-Foreman distillery, and uses old whiskey barrel staves for smoker fuel. Unbeliveable odor !!! and a very sweet smoke flavor. He makes his 'secret' mop and rub...but it is related to the K C sweet style would be my guess.
Here's another view
