Thanks.
Home today catching up on farm accounts, not helped by our internet service cutting in and out.
Once free of my Fieldays commitment, I will try to make direct contact with the holder of the photo, and enquire about their NZ connection/s.
The photo will probably be of a 1930's dairy company factory. In full view is a landing bay for receiving cans of milk or cream. But taken in the 1940's or even the very early 1950's as it appears that the original building was added to by a much bigger processing building.
Milk tanker collections of milk started in the Waikato, in the very early 1950's and rapidly expanded throughout the country thereafter.
Alan.
