ZB is tyre placard 9946869. This suits NON HZ Sandmans with 2200kg GVW.

Sorry so thats not a good start.

Looks to be a base model sandman optioned with bucket seats and the comfort package (full hoodlining)

Only thing id be interested. Does it have a white fuse holder on a red wire hanging out of the wire harness in the engine bay. Inbetween the booster and the wiper motor.
