1930's german gescha clockwork diecast trick car ( boxed)

An extremely rare pre war toy die-cast saloon car that was made in Germany by Gescha (Gebruder Schmitt).
The car is called a Sixmobile.
It has built in mechanism that means that its movement is completely random.
It is clockwork and comes with the original key and remarkably, its box.
It is missing one headlamp and a small piece of wire on the underside which attaches from the lever to the front axle.
Otherwise is superb condition for its age.
Dimensions 4 x 2"
