Pictures from the scene that can be seen sometimes on TV still.
The boy called the Sandmann to bring back the bird to the girl.
Swiftly Sandmann arrived to bring back a colourfull bird that escaped from the girls balkony but was shy to return.

Thats what the Sandmann told the children. Behave nice, be helpfull, respect each other.
Well done.

TODO: make the new base frame & cabine.
Overcome the restrictions artificially created by stupid new western Sandmann assets IP-owner claims.
Do measuring and scaling up data taken from a poorly made (of course chinese made) 1966 made car modell instead of using the original makers drawings they keep hidden from the public.
Example, see the roof of the cabine. On original it looks like a squished circle.
The dumb chinese made it a round circle instead. Heck.

These drawings DO exist on the genius Harald Serowski's sketch book, but they keep it a secret.

From old postcard the car (the version before the red PU-247) on black/white picture.

As usual all credit goes to the genius Mr. Harald Serowski and team at the former GDR TV puppet studio.

A series of vehicles started with the universal service car shown in the role of collecting garbage and paper for recycling.

Basically the chassis of the Sandmann service and firebrigade cars are the same.
See the side by side picture.

The ladder mechanics parts will be the same one used on the service car.
