One car, three names: Sperber, Colibri, NAW (update: 1915 Sperber)

The Owner of the Sperber was listed as a car owner in 1915. Because of the WWI goverment gave an order to list all owner of mechanical vehicles that is autos, motorcycles and motor boats. So this Sperber car be earlier model like 1913.

This car is a NAW Sperber, not a Colibri. NAW, the Norddeutsche Automobilwerke (northern germany car company) was located in Hameln, today lower saxony. From 1908 on the Colibri was produced, a very small car, but it is definitely not a Colibri, as instead of "NAW" Colibris had the name "Colibri" pressed in the brass radiator frame. The Sperber was produced until 1919, when Walther von Selve, who had financed NAW since 1917 changed the name of the company and founded the "Selve Automobilwerke GmbH" in 1919. If the date is right, this is one of the latest Sperber, as in 1915 production of cars stopped and NAW concentrated on the production of military things. NAW produced about 800 cars per year with Export all over the world. This 1915 model is of the second model type of the Sperber, the first model also had the name pressed into the brass radiator frame.
