Would really like to know what these are and what they were used for?
How about helping us a little bit like giving us a size reference, general area of the country, farm or urban, where you came about them.
They are about 5 inches tall and quite heavy for the size of them. The top unscrews and the two middle round pieces are felted on the inside. I bought them years ago at a yard sale in a small rural town in Northern Ontario. Not really farm country but there was a large iron ore mine here.
The felting tells me they were clamps for something with a surface you didn't want to scratch.
What about the bottoms we can't see? Screw or mounting holes, or do they look like they were made to just sit flat on a surface.
They look like they were made to just sit flat on a surface. Thanks for responding.
I wonder if they were some kind of weight for holding curtains or portieres in the desired place.
Its designed to clamp on a close fitting round piece such as a wood rail or tubular metal.
If the supports pivot, the construction is not quite right for an oar pivot on a row boat.
Looks similar to the weights that hold down the foot rail on our bar. Ours are timber like the bar and attached though. Can imagine they would do the job just fine though try researching old bar's or ornate bar's you may get a result.
