I remember that stuff....had a set when I were a lad....
Wow, that was a few moons ago, but as I recall, it had electric motors and gears to create motorised cars, trucks and cranes, etc.....fantastic stuff, that Meccano. Got it for my eighth birthday and kept it up until I was sixteen....
Luggage restictions didn't allow for me to bring to Oz, so I gave it to a cousin, whose kids were still playing with until they grew out of it just a couple of years or so ago. Wow, they don't make toys like that anymore. These days Meccano is mostly plastic, whereas the set I had was metal with brass nuts and bolts for assembly, brass pulleys and gears for all the moving parts....wonderful stuff.
Ahhh, those were the days....
