We had a big box of it at home in the 60's too which belonged to my brother, but I never felt the urge to have a go at it.
This was the era of slick E-Type Jags and space rockets, but to me Meccano just seemed to be stuck in an age of old steam tractors.
There was also an element of Frankensteins hideous monster creations about the concept that was a bit off-putting. Why would you want to make your own ugly sub-standard vehicle when you could get a stunning Corgi ready-made?!
This aversion to it however is more a fault with me than the toy I suspect because I also didn't take to Metalwork at school, and the only time I've ever been sent to the back of the classroom by a teacher because I showed no interest in a subject, was for Applied Mechanics!
Meccano - nah, sorry, not for me.
