First registered on 13/10/1967 I am interested in finding more about the history of the vehicle, I believe she is ex MOD as has a repair patch where the 2nd fuel tank would have been, has a diff guard and I think maybe the remains of what may have been an axel guard, and a duel fan belt fan.
Any pointers would be much appreciated.

There should be an aluminium nomenclature plate fixed to the seat box or bulkhead roughly double the size of the chassis plate, on it should be its contract number and military reg number eg, 23 EK 45. Post some photos of the cab and other parts of the vehicle as we can help.

Brilliant thank you, will have a look.
