Hello Don, nice to see your Hornby loco. It is an original one of course, the color of that model is more redish than the JEP one which is brown. All those colors are not realistic, as they where toys and far from scale models. If you enjoy French Hornby there is also another color variation which is less common in brown.... also a black one and the oldest was green...
That's all for the post-war models, Very Best, Daniel
