So with my pride swallowed, I try to investigate the variety of ways this can be executed. With the opening statement being 68's split (with 68A [468]'s birth) intended to be at Herne Hill rather than West Norwood. Fun facts eh, too bad 40 decided to outright leave for Dulwich.
I'm questioning why I've done this but I've put the effort in anyways so I've seen it through to the end.
