Is anyone aware of a complete list of all and B roads starts and
ends?

eg A34 Southampton-Manchester

Trouble is that many of the old trunk roads have been carved up and lost
their continuity with the building of by-passes and motorways,
being renumbered as 4-digit A roads or even B roads for whole stretches -
e.g. A46 Bath-Lincoln (which for instance is superseded by the
M69 between Coventry and Leicester - why didn't they call that the
A46(M)?)

For example, the original A42 was from Reading - Oxford - Birmingham. The
Oxford - Birmingham bit was renumbered to the A34 when this was extended
from Oxford to Manchester, so until the M42 extension to Nottingham was
built there was no A42 for many years.
