Like he said, it came with a WCFB. Carter didn't give flow ratings on them, but they weren't very large; usually in the 375-450 cfm range.
...you are familiar with how a browser search works, right? As mentioned, Carter never gave cfm ratings so we can only guess. Given the physical size of the venturi and ****erfly I'd think that 400 is optimistic. .
They might only be 400CFM, but keep in mind that in the 50's a foot was a lot bigger than it is now. In fact, minutes were longer, too.
