54 complete B-block peals 

I have found 72 sets of round B-blocks which together with some B-blocks exactly cover the extent in an odd number [33 to 45] of round blocks where the sixes can be rearranged to give 55 complete B-blocks. Some of the sets of blocks which give peals are illustrated below.

These are blocks from a 3-part group so give irregular, but not exact, 3-part peals

39 round blocks, signature 54:9+105

These are curious blocks - some are repeated, some are not.

Not an exact 3-part, but reasonably regular
