Jerry thats what i was thinking myself but i did find this on an Austrailian Rover site.

1981: An Isuzu 4BD1 3.9-litre 4-cylinder diesel engine was a factory fitted option in Australia.

If I were a betting man I would also say that the engine was produced on or before 1980 because I have done quite a bit of research and have found no type of picture to confirm the engine.
