I think they would be perfect for someone who is designing a custom architectural piece, these would make the piece one of a kind and absolutely stunning in my opinion. They are made of Cast Iron, with metal and rubber wheels. Structurally they appear to be sturdy and strong. Each one weighs approximately 3.10LBS each!
They are most likely well over 100 years old, but I do not know their exact age. They were used for many years on some kind of cart so their cosmetic condition as you can see in the pictures has tarnish and some rust and wear to the rubber wheels and chrome near wheels mostly worn away.The inside of the cast iron (which is barely visible) has more rust which could be brushed with appropriate tools. Even with the expected century of wear, they truly are rare spectacular piece(s) full of spirit and history!
The wheel diameter measures approximately 6" and the overall height of each caster is approximately 9". The first picture is all 4 casters, the second picture is the reverse side of the 4 casters. The other pictures are close ups of each side.
