I spy a Golden cane mill in one of those pics--a one horse mill. Got a double here--A columbus #18 improved--took at least 2 mules to power it. You can tell the difference between a single team mill and double by the shape of the beam bracket on top. If it just slants down on one side, it's a single. If it's an inverted V shape, sort of like /\, but less angle, it allows for a beam to come off each side, with each harness beam to get a team.
Man, there's some really messy buildings !!!
