Hornby OO Class 142 Pacer Twin Railbus Regional railways Livery Boxed

The Class 142 DMU is in very good condition please see photos and runs really well in testing, I have noticed there is a small gap between bogie and body on these but after looking at others they also are the same on the 142 but put in to be clear and can be seen in pictures, please note unlike some models both these units have power cars, this model also comes boxed please see pictures for condition, cellophane is split and box states R867 but when I look I can only find R346 for this model in Regional Railways livery.
