The catalog also carries this part under the older number B52A, which is the earlier reference some Norton parts books still use. If you've got a parts list with that number on it, it's the same physical component.
We don't have more detail on this one beyond the basic listing. If you're sourcing this for an ES2 rebuild, give us a call and we can confirm it matches your specific engine before you order.
