"The Nobel-prize-winning physicist Richard Feynman wrote about his early childhood experience repairing transistor radios in the 1930s."
They would not be transistor radios in the 1930s. Battery radios had valves/tubes in them and two kinds of battery. The picture is a very late 1950s/early 60s transistor radio.
Nice site, interesting content, have you ever come across the British judge Lord Denning? He was a mathematician to begin with then turned to law having decided that teaching was boring.
