Here are two antique cast iron and porcelain caster wheels. I don't know what their original purpose was but they have double wheels and swivel. They measure 1 1/2" across x 2" wide and the wheels are 1 1/8" wide. There are no cracks in the porcelain and they have not been cleaned, all patina is original. Together they weigh 13 ounces and will ship free via USPS ground to the lower 48 states please.
