Unfortunately, my oldest 'Practical Television' magaizes are from 1952, I
think. I have about 3 years worth from then, then a large gap, another 3
or 4 complete years in the early 70's, then another gap, then everything
from the end of 1985 onwards (until a couple of months ago, when the
editors changed, the new chap is, I believe termially clueless, so I've
stopped wasting money on it...)
