Ive had 2 HZ sandmans that were both still in their original paint from the factory. One was a Melbourne build and one was Sydney. The Melbourne build had black paint under the cowling grill, and the Sydney one didn't. Not that anyone really can see it properly but just thought that might be of interest.

They were also both done slightly differently at the back of the doors. One was a larger blackout that the other. You can see that on the turquoise van, the blackout comes further onto the body that the Mistral grey ones does. The Grey one is Melbourne and the turquoise is a Sydney build.

Unfortunately I wasn't smart enough to get photos of what Im talking about with the cowling. Heres both of them in their original paint though which might help.....
