Having just read all the above items, & have suddenly realized why, on my model "Windsor Lad" i have two shades of green along the boiler, the front section behind the smoke box between bands 1 & 2 is a darker shade of green than the rest of the locomotive, but saying this, it does not detract from the over all beauty of this loco, I have also installed a DCC chip into it, without to much trouble, is there a difference between "Windsor Lad" & "Flying Scotsman" that makes this install more difficult? Finally i must add that this loco is now the pride of my fleet, its smooth running, quite, and a delight to watch trundling around my layout. Nice one Hornby.
