So, I think in terms of numbers not modelled, we have:
50001
50003
50005
50006 first in refurbished blue
50009
50012
50014
50016
50017 LMS crimson?!
50019 Laira DCE blue?
50022
50023 - some good options here I think - ghost white, large logo blue but with small logos?
50025
50026 early NSE with black window surrounds
50028
50029
50030
50032
50034
50036
50038
50039
50040
50041
50042
50043
50044 BR two tone green as preserved?!
50047
if duplicating, preservation era Loadhaul and Intercity
considering it’s been around for the best part of 20 years, that means that including limited editions (but excluding some duplicates e.g. 50007 about three times, 50037 etc), that’s an average of about 1 per year. 30 years to get through the class!
