Many people will no longer know what I mean when I write the word, Meccano. When I was a lad, it was the world's equivalent of Lego, but made out of metal and much more flexible. People used to build great models of engineering machines and such out of it. I wasn't ever much into it, because I'm not really a building-sort-of-person, (being creative in a different mode) but I've seen some extraordinary uses made of it.
While checking out some info on a 1930s analogue computer made out of Meccano (I kid you not!) I saw a link to Meccano and Divorce. Obviously some people still horde their Meccano sets with a fervour that is usually only reserved for gold, silver and other precious jewels.
