How many Geviva Mk.4s were produced?

I know of these 3.

The V8 powered one, still in Tasmania.

And the two Alfa powered ones.

This one in country Victoria.

And this one that recently moved to Albury and now has the customary stripe through the centre like the others.

Were there any more?

As you can see they differ from the original by being more slab-sided rather than the sills curving under the body.

STOP PRESS! I've just been told by a reliable source that the silver and green one is an original Mk.4.
