Does this description make sense?

I'll add to the above point. The reason I made the suggestion above, is if you spend about a month or two making Radio & TV news bed time reading, you will essentially get into the head of a mid 20th century TV service man. They had articles on running a business, articles on new products, articles on how to test things, "tough dog" repairs. It's basically a slice of the whole industry. The Mac's column was a narative about a fictional repair shop where "Mac" would solve a couple tough repairs, with the help of his teenage assistant "Barney", and they would banter about current issues in TV/Radio repair, along with some corny material about Barney's girlfriend, or some sexist comments about female customers. It filled about a page to a page and a half, in every issue of Radio&TV news through the 50s. And the advertisements are a huge source of info too, giving more insight into what was going on at the time.

Technical books may be more to the point, but they are usually more dry, and don't contain the "human" element like magazines do. I think considering what you are trying to do, knowing a bit more about the "human" element would work well for you. Particularly things like how business was conducted, what customers expected, what a service call consisted of - the layout of a shop, the general demographic and social status of a repair man, etc. A bit of research will bring all this stuff into clear focus.
