I was reading about it here, and it pretty much tells why it's there and what it's supposed to do. It's on page 117 and page 118 of this pdf. It's exactly as Prof Marvel said. I can't find a drawing that actually has a scale on the same picture, but I'm bettin this little chamber only holds a smaller charge than you would ever play with (in reference to worrying about not filling it up). But, that's just me looking at it. I didn't scale it into my cad program. It was interesting, but not that interesting.
