I'm pretty sure a lot of those are jet boats, so my guess it was probably taken in NZ, most likely South Island.

Great pic. I wonder if he can date it at all (?).
Not many any on the line there, I wonder if it's just a special or specific part of the factory where there are only a few at a time, or maybe near the start of production.
That picture is in John Smith's book, and is titled "Production Line 1948".
