[r-t] 41 Surprise Minor

It seems to me that the following trivial but useful simplification is
possible in John Warboys' beautiful and already "classic" bobs-only
41-spliced composition. Perhaps John or somebody can check whether or not
I'm being stupid here.
The London-above block of SU0308 finishes with a bob, bringing up 34256 as
the first part end. However, this bob can be omitted, since it will not
come round after one part, so doing so just rearranges the three parts. As
a result of this, the part now ends with a plain lead of Co, so the
instruction "in part 3 call Li for both leads of Co and Co for both leads
of Li" (which was presumably included to ensure a plain lead of every
method) can be omitted. (Li and Co are lead-splicers). Finally, since
the substitutions of We for Lo must match the substitutions of Nw/Ak and
Mo/Ct in the earlier blocks to get proper 3-lead splices, we must now make
sure we do them in part 2 (which was part 3).
So we get:
23456 Lo Ke Lo
- 23564 Li Li
- 45236 Lo Ke Lo
- 45362 Co
- 56234 Cu Co
Repeat twice, in part 2 call We for all 4 leads of Lo.
Not a big change, obviously, but every little helps the novice conductor!
