Tillotson HR40a?

Interesting.  I recall a similar finding when I looked at a BDC-16 in some depth a few years ago.  (Cavities within that serious-looking four-plate pump stack weren't connected to anything.  I figured they were left over from some other application; probably recirculator.)

What were the reason(s) to block off the unused passages? Just curious.
