Hi blownbudget.

Post the rest of the tag details if possible. Im assuming its an early HJ Panel Van pre-9/75 and as such it is similar to a HQ to identify. The HJ PV should be a base model with at least the correct console mounts on the floor. Part of the identification is with the rear headlining fixtures which were unique to a HJ. Take some photos of the rear of the van and look in the glovebox for the tyre placard and note the number at the bottom.

Welcome and hope you have found your Sandman. :-)
