400 cfm AFB?

Yes, they did. They made a 400, 500, 575, 600 and 750 cfm stock size AFB's.
AVS's were 2 sized @ 630 & 750 cfm

I'm poking around now for the WCFB sizes. OH, there it is.
Rated @ 385 cfm and 18 lbs. of cast iron, Intro'd in 1952.

Wow 18 lbs!! I remembered they were heavy but not that heavy.

Didn't they make a 625 AFB also? I remember reading several places where they mentioned the small one being 625 cfm.
