Up for sale here is this vintage Walsco idler wheel / roller wheel. This is new in the original package, and the rubber is still soft. This is guaranteed to be good.
Please be sure this is the exact wheel you are looking for before you buy it. Please see my pictures for details.
US shipping and handling is $5, and international is $18. If you have any questions, please ask.
I have a number of other idler wheels, collectibles, and vintage electronics listed--feel free to take a look!
