Thanks for the reply Robert!

Here we see the front of a painted prototype or preproduction car (top). And we see an unpainted prototype (bottom)? Both pictures from the same book as the one in post nr. 2.

The front has a completely different front bumper. The plexiglass hasn't got the trim round the center, where as production vehicles do.
Notice the Alfa emblem on the bonnet? It looks like a black and white version like they used earlier in history. Different too. Notice the Alfa Romeo emblem on the far right?
I do see some contours of the separation plates that channel air to the radiator but I do not see the slots in the plexiglass that feed air to the carburettors.
I have reason to believe that this front belongs to the car discibed in the second post. The front looks painted and on the floor we see tools as we do in the picture in post nr. 2.

The unpainted prototype is discribed as the original prototype chassis. The book by Michele Marchiano says; 'The tail was truncated, like that on the TZ - the classic expression of the Alfa/Zagato partnership. At first the design followed that of its famous forebear with the tail curved into a prominent lip. Both the scale model used for wind tunnel testing and the prototype shared this feature. But the design was dropped as it would have created assembly problems and increased the cost of the moulds'.
So this could be the first prototype of the Junior Zagato on full scale.

And look at another picture of the preproduction car. It has the exhaust further to the left although the cutout in the bumper is still more in the middle. No 'Alfa Romeo' emblem on the rear, the license plate lights look different from the production model and the 'Junior Z' on the right hand side beneath the rear light cluster is missing.
The trunklid seems to have the normal length beneath the glass part. Could this be #1800002 that was painted yellow according to Michele Marchiano?

Ciao, Olaf
