During the Second World War the content and quality of the magazine was reduced greatly, and the size decreased from approximately A4 to A5.

In 1963 the magazine started reporting a loss and Meccano Ltd handed its publishing over to its printers, Thomas Skinner.

In April 1973 it was resurrected again, this time as a quarterly magazine, and from 1977 it incorporated Meccano Engineer and the Meccanoman's Journal.

Aside from Meccano related articles, it also featured Hornby trains, Dinky Toys and other products of Meccano Ltd, plus a wide variety of general interest articles, including, engineering, aircraft, trains, modelling, camping, photography and philately.

The magazines today are an excellent source of historic information and an invaluable aid to collectors of toys from those years.
