Dresser drawer wheel needed

I have an old armoire where the rear wheel from one of the drawers broke off. I was able to put it back together (including the little ball bearings) and using a wood screw through the center, re-secured it in place. When making the repair I discovered the same wheel was missing from the other side of this drawer. It must have been like that when I purchased the armoire,

Rather than try to replace the whole sliding hardware, I just need a similar wheel that can be screwed through the center to remount it. Is this something you sell?
