Atomic Ranch is a lovely resource -- but you won't know how much of what you're seeing is someone's take on the period, as opposed to what's genuine -- it seems to me. You want an original source, photos taken in the period, to get an undiluted take on the scene.
Here's one, with pictures of 50's kitchens. You can probably find photos of other rooms by substituting the word for "kitchens". . .

I think you're on the right
track. Like House Beautiful, many other magazines must have some online presence, including archived old issues ?
