thanks, Brian,
I do not know - apparently it was previously registered in Ireland but as far as I know there is no previous history before that.
This is the problem with something like this that can well have been cannibalized in previous military or non-military life.
The DVLA require proof of the date of build of a vehicle before they will issue an age related registration number. My mistake on the cab (senior moment) but if the worst comes to the worst I will try using the engine number as proof unless anyone can tell me where to find a chassis/build number xcept on the original dash plate.
