I am now the "Chuffed" owner of three x bachmann 45xx locos, these being the BR black, lined green and collectors club sloping tank versions. Trouble is, while looking through "Great western branch Lines 1- The south West" by Michael S. Welch, on page 71, it shows 4566 as a black (looks unlined) loco taken on 11th June 1961 while Bachmann have produced it as a green lined version with late crest.
So, is there any sort of archive / records of when locos went into works for overhauls etc and when they world have changed colours?
