About sixty educational models of machine mechanisms are preserved at Kyoto University. The models imitate the movements of basic machine mechanisms, and model manipulations via handles enhance students understanding of machine mechanisms. It is made clear from the labels on the models that twenty one of the sixty models were imported from the two German companies in about 1900. One of the companies was in Koeln, and delivered on the domestic outside for demonstration or education, advertising a true copy of the original in the most minute details. Then, between the end of 19th century and the First World War, Germany was a co-leader as well as America in the export and the output of the machine industries.
