[UK flag] -- Meccano, the British-built construction set, is engineering in miniature. It enlarges a child's intellect by encouraging him to use his brain, eyes and hands.
    As he builds, he discovers how things work. He learns about form, scale, perspective. Basic physics principles. He develops manual dexterity. Patience. And he expands his inventive capacities and imagination by building models of his own design. 
    For 70 years, Meccano has been making the finest construction sets in the world. Using precision-engineerd parts, so tough they can take the most enthusiastic handling.
    We believe that constructive play helps build constructive people. Meccano turns a boy's world into a man's world.

Color of models may differ from illustrations.

Note odd spelling of word "manoeuvreability".

Text in red frame: Mechanisms -- Extra parts add mechanical action to Meccano models. Makes dozens of mechanisms --illustrated instructions to build 27. Can be used with any set from No. 3 upwards.
 

Text upper left corner:  The Meccano Mechanisms builder has the chance to learn, and understand easily, a great deal more about engineering principles and the way in which machines are made to perform their various tasks. And he can apply this knowledge to a whole new range of real working models that come within his scope with the Meccano Mechanisms Set. He can adapt the mechanisms to fit models he invents himself, put controlled action into them -- make them work like the real thing. The Meccano Mechanisms Set adds a whole new dimension to Meccano model making, with the variety of mechanisms that can be created from this one set. Meccano makes true-to-life models -- the Meccano Mechanisms Set puts real life into them.

An easy way to show how the motor car works. 
Each of these car mechanisms is interesting in itself. It is very easy to see how each one works. This gives a youngster -- even an adult -- an excellent grasp of how a car works. And when you have seen how the mechanisms operate, you can build them into a Meccano motor car to make it go just like the real thing.
