Maker of radiators for a whole host of mostly vanished British-made trucks.
The "Withnell radiator tube" (also known as a "Joule tube") has replaceable cooling tubes seated in rubber grommets between the upper and lower coolant tanks to better withstand vibration and pounding, especially in heavy off-road equipment.
Six years after this ad was posted, Norman Isherwood & Co. at Bolton & Shipley and Marston Excelsior Ltd. at Leeds were combined into one company, Marston Radiators Ltd. by Imperial Metal Industries Limited. In 1989, the company became DENSO Marston Limited when it was purchased by that Japanese company to make and supply car radiators for the new Toyota factory in Burniston, Derbyshire . In 2007, it left the car market to focus on cooling systems for non-automotive applications. It is the only company outside of Japan to be awarded the prestigious "Mother Company" status. The company's website states:
In line with DENSO’s vision of steadily reducing environmental impact in global production, DENSO Marston has been a zero waste to landfill site since 2009. Our grounds are also home to the DENSO Marston Nature Reserve, helping to offset carbon emissions whilst also giving something back to the local community.Impressive! You don't see many North American companies behaving like this.
