One of the premier miniature model companies of Italy was known as Dugu, a company that produced some beautiful models in scales 1:43 to 1:50.
The company started in 1963 by marketing Miniautotoys and Museo models. They represented real cars from the automotive Museum of Torino, Italy. Miniautotoys are high-quality 1:43 scale models similar to Rio, while Museo models are 1:50 scale simplified, less expensive models. A third series called Sispla was also produced in 1974.
