A range of model toy cars produced in Germany by Mr. Wittek, operating from a suburb in Düsseldorf. Ziss is largely noted for its models of veteran cars, however, a good selection of other vehicles -including modern cars- was also manufactured.
Production was essentially during the 1960s. The toys were first released as RW-Modelle, and subsequently as Ziss-Modelle.
After the death of Mr Wittek, his son continued die-cast production with the Ziss brand name.
