Tin-Plate, Wind Up Helicopter.
A rudimentary toy, it is full of charm thanks to its lack of sophistication...
Nicely lithoed, it is powered by a clockwork mechanism which winds with a separate key (included) through a hole on the left side which drives the front wheels and powers the main propellor. The tail wheel is set so that it will drive in larges circles.
It comes in its original, colorful but somewhat battered, box.
It measures some 7.5 inches in length.
This helicopter is for collectors only and not suitable for children!
