Found on a neighbor's property at 8000ft in Jefferson County between Evergreen and Conifer.
There is a log cabin ruin about 300ft away.
It's slightly ornate, beyond just practical shape. The four iron sub pieces can spin on the bolt axle, however, the bent "handle like structure, which is partially broken off, would (if unbroken) prevent even the smaller armatures from spinning even 180 degrees.
The two larger armatures have a lip on one side, facing each other. This lip seems like a centering rim almost like it would support a cylinder between them. Picture a toilet paper tube holder, except it's clearly not that and the bolt isn't long enough obviously.
There are what appear to be countersunk screw holes on the three more ornate armatures. The fourth one is a plain rectangle with no holes other than the center. It does taper slightly in thickness to the ends.
