Was very surprised to see a picture of a Holt tractor on the Dutch site of national archive.
There was no description of the photo, only Photo collection Dutch Heidemaatschappij.
Then my curiosity was only really awakened.
Nederlandse Heidemaatschappij
On 5 January 1888, NHM was established with the aim of advising on and stimulating the exploitation of wastelands, the construction and maintenance of forests and the construction and maintenance of irrigation and soil improvement works. In 1897, there was still the development and improvement of the freshwater fishery. The work quickly expanded from advising to carrying out work. Clients from outside the member base were also served. This created an ideal association with a commercially functioning work apparatus. However, the association's association with the 'general benefit' objective and the market-oriented work organization was increasingly seen as problematic. That is why NV Heidemaatschappij Beheer was established in 1972 as an independent work organization with the association (now Royal) as sole shareholder. With this privatization, the association (KNHM) developed a new policy that focused on the areas of focus of land development, living environment and the environment.
