(Grand Forks, B.C. Canada)
Another one of those strange things I find when renovating old houses. This is a knob of some kind, and various possibilities have been suggested. Someone thought it was a gear shift knob from an old car, but it's so heavy and cold, being brass, that it would be terribly uncomfortable. I have no idea what this would be.
Woman of Many Sticks reply;
I was puzzled about what this could be too, but I think I have an idea. It looks like the top of a 'hame' which is part of the horse tack that goes over top of the collar part of draft horse tack.
There are two of them, which are tightened so the collar stays in place, and the horse can pull a lot of weight. The fancy dress tack used in parades or for the Budweiser Clydesdales is usually brightly polished brass, with decorative brasses, which are flat images that can be attached to the leather straps, and brightly polished buckles everywhere.
See the picture labeled 'old hame' to see where the brass knob would go, and see this image for a full picture of the collar; Harness, collar and hames
