Hi Les,
Confess Wireless World was ever well over my head, and probably still would be with all those Carbon nanotubes, String theories and many other dimensions where one might meet oneself but with either several /or no heads/or any jolly creative bits.
Seem to recall, our FJ invented a 'built in' Camm driven bicycle pump (Practical Mechanics) for folks with a slow puncture - Never got such stuff in 'Radio Contructor' it was just 'Dicky and Smith' - bit like the 'Archers' but with no instant death, just leaded solder and Mercury switches thought to knobble us later.
Then, in the 60's we got generous X rays, but some good Test Card films - still surviving and trying find another old 'Bull-Nose' Morris to sort - Chris.
