Ha! For some reason when you said hunting for Uranium deposits was popular in the late 1950's the first thing that came to mind was Ward Cleaver smoking a pipe and telling Beaver to be careful with his Geiger Counter and to stay out of trouble while Beaver skips out the front door with one of his buddies on a Uranium hunt.
Can't wait for people 50 years from now to look back at us and think, "What were they thinking?! Didn't they know how toxic handling transistors is?" Or whatever we're doing now that we really shouldn't be.
Oh, yeah - that's another thing - invariably, at least up through about 1958 or so, every man (unfortunately, that honestly is every "white" man - but that's another topic for another thread - that and the mysoginistic viewpoints from the era) picture seems to almost always have a pipe in their mouth. There's one interesting article about underground RF coaxial lines being spliced "delicately" by a repair guy; he's got a pipe in his mouth down in the trench!
Then - I guess the ball started to roll on how tobacco and smoking was causal for lung cancer and other ailments, and the number of those images have gone down past about 1958 - but they still pop up occasionally.
I'm going to continue to read the issues forward in time until the following three things occur: Model Garage disappears, Wordless Workshop disappears, and "how-to" articles disappear; I'm pretty sure they happen in that order, too, and the how-to articles likely drop out sometime around 1978 or so...

: I think you've hit the nail on the head, so to speak; though likely more so on the latter than the former (western society loves it TV, and other than seemingly making some of us dumber, as far as we know it doesn't cause cancer or other illness).
