You'd probably find that TfL's museum at Covent Garden has something in
their library of maps but you'd need some form of authorisation to look I
think.

Perhaps if someone comes along and offers me a sabbatical (do grad
students get sabbaticals?), i'll take a year off to collate and digitise
every scrap of information available, then put together a definitive map.
Or persuade some geography student that it would make a good dissertation
project!

When the tube system is shown on a geometric map it is almost always done
in a way to assist users of the map to find routes. To do this it is
inevitable that a lot of fine detail has to be compromised in order to
maintain clarity.
