Oster Versa Blender Base and Chopper blade bowl. Read descript

I’m selling this either together or separately. The reason is this bowl Eventhough sots well on the base, doesn’t match the driving engine spindle. Base works well. It has a square pin. And the bowl has a different shape opening. They don’t engage together. The bowl doesn’t have a plunger. Although for this blade that is only for grinding and chopping at the bottom you won’t need a plunger. Plunger is for a different blade that sits at the top of the bowl. I don’t have those.
