A few nice history images I found:
The dairy in Vevey (1890)

Image by Nestlé
Originally, Henri Nestlé bought the milk needed for his baby food each morning but by the summer of 1869, two years after launching the Farine Lactée this was no longer practical, so he to buy his supplies from a milk collection centre in a small village near Vevey, from where it was delivered to the factory.
