Cast iron ore cart wheel set 5 inch for large model mine car mining

Description

Set of four cast iron ore cart wheels. New wheels made in the USA measure 5-1/4" outer diameter across the flange, 1-3/4" wide with a 3/4" axle hole.
Photo of finished cart for reference no other parts are included, only four wheels.
These are for display use only.
These wheels are accurate representations of ore cart wheels made in the late 1800's, sand cast as they were then, therefore will have imperfections such as small voids, bores not perfectly centered, etc.
Thanks for looking.
