Much obliged Steve. I'm afraid that I do not have a copy of said Collection :-(
However, since you speak of
"a singled-in block of 15 leads in place of 5 singled-in B-blocks"
I assume that the original 5 bobbed blocks happened to have a plain
lead q-set to link them up and what would work is if the blocks
contained the relationship:
Then omitting initial 3rds (as per New Grandsire) the blocks would
link together and the whole if inverted would now ring as Grandsire
proper...a single to link any of the bobbed leads (ie former 'normal'
3rds) to the main comp would do the trick....However this IS an
exceptional condition (that 5 otherwise isolated bobbed blocks could
be linked by initially ringing New Grandsire on them) that I feel that
my original statement stands pretty solid
