From blacksmith to milk collector
In 1930 blacksmith Siebe Koopman of Briltil (close to Zuidhorn in Groningen) notices a drop in his income. More and more of his customers, mainly local milk collectors, are exchanging their horses for lorries. Siebe Koopman starts a taxi firm. But the cars are not used enough to generate sufficient income. Siebe Koopman therefore decides to make a living from milk collecting. This gets off to a successful start and during the course of time his sons Klaas, Henk and Piet join the company.
