Right, and in this case for Beverley, it misses 4 rows that are xxxx61 (I 
think they're all of that form, my notes on it are in my office and I'm at 
home now).  These rows can only occur when the 6th is 3ds place bell, and 
ringing those leads as cambridge is sufficient to make it true.  It looks 
like you can mix and match the other bells as 6-lead splices freely, but I 
didn't check all combinations.
