Siemens is the company that has taught many engineering elements to more than 10 million technical and commercial employees, excluding Vendors, Customers and business partners, for nearly 160 years. ONLY about 10,000 of them set up their own businesses as Entrepreneurs in the steps of Werner Von Siemens, most otherwise larger for society. Of course, we are far from such a "technological level". Especially touching is the painting of the tank from the spray gun and the impregnation of the coils in the groove from the barrel. It is a pity that the manufacture of the tank and the cutting of the lamellas for the magnetic circuit are not shown.
