The detail changes are fascinating on this model, for me the fact that the flat end is accurate for a particular works in Derby has sold it for me, I'm pleased the buffer beam issue can easily be sorted as that would bother me. As for livery I could overlook this but my purchase will definitely be green, I've even considered green full yellow ends and tops numbered aka 25043. What a nice day to ponder my purchase, it's driving my wife mad though she just doesn't get it! I am a convert to this loco now shouldn't have doubted it in the first place but we all make mistakes!
