This is one thing I've wanted to do for a while, and an impulse purchase convinced me to do it. For the cost of the model, detailing kit and other parts needed, it comes close to the price of the Hornby version. Having said that, this will produce a far better version than the standard model available, which has many errors originating from it's Airfix GMR origins.
As you can see, it's got a long way to go yet but it'll become Oliver. Eventually.
