The January 1928 issue of the Meccano Magazine with an image on the cover for the article on the building of the Panama Canal. Many more articles inside on various feats of engineering, science and of course Meccano.
Also in this issue is the first instalment in a series about famous inventions. The header of the series contains a list of notable inventions. There are the expected items such as the steam engine, the sewing machine, the motorcar and the typewriter. Oddly missing (for '28) is radio. On the other hand it does mention noctovision. But to get back to this first article - the story of the invention of the typewriter.
The article gives a quick historical long view and then goes into more detail on how the 'startup' of Glidden happened, including the 'pivot' from a numbering machine to the general purpose writing machine. (To put it in today's terms.)
All back issues of the Meccano Magazine can all be read online at the Internet Archive. This link opens the January 1928 issue, browse to page 10 for the article.
