Side view.

Actually... looking at that a bit closer that's a Comor not a Dodge This must be a 76 model N reg?

To be perfectly honest I can't remember, you could be right, it was ex GPO and I had it in the mid 80's, bought it from R.C. Harding at Long Rock.

Think! come on you must have an invoice somewhere

Just realised this is the Commer space van.... wow! Cult stuff indeed. Your van has wrap around steel bumpers... although the dodge did as well the stopped at the edge. Basically the earlier the model the more the bumper wrapped.
The age is purely a guess because before 76 they had glass cone stop lights and separate indicators. The sides of the vans were almost identical throughout production except.... BT vans had a side door as well.

Commer sounds right, I'll see if I can find more photo's, paperwork would be a bit more difficult as it's 20 odd years ago.
