One example worth citing is that of a patent in 1949. At that time, the company had just designed the revolutionary slotted handle of the water pump wrench which is known affectionately as “No. 188, the red one with the yellow dot”, of which the latest version is still included in the VBW catalogue. Based on the same patent, “No. 966 in red” has continued to keep a firm grip on the world. It is still the water pump wrench with one of the highest sales volumes worldwide. In this way, VBW and the colour red have been a decisive influence on the whole industry.
