Clive,
The vehicle was manufactured on 18th October 1979.
Army Transport Museum says vehicle came into service January 1980 Sent to Operation Agila initially prior to returning to UK.
Vehicle log book says Colour: Green. No other codes are present.
Ideally I would like the original colour although if it was different for N Ireland, let me know as that is now where the vehicle resides.
I assume any colour is a Matt finish?.
