This is a great link. I have a box of old Model Builder magazines somewhere up in the attic. The magazine is great not only for its still useful how-to articles, but as a slice of Americana and history. The magazine began at the height of the depression and shows how much can be built with scraps of lumber and cardboard.
I just looked at the first issue with an article on making your own cattle crossing with corrugated cattle guards. Who even knows what those are today? It reflects a time when farms were a much more common feature of American life.
