Vintage Double Hose

As a boy in grammer school in the early 50's I remember many articles in National Geographic by JYC. Does anyone have any of these issues or have seen them for sale. They were some of the first articles I ever read about diving.

As a kid in the sixties I remember an article in National Geographic about salvaging a Spanish Gallion. That was one of the many things, like Seahunt, Voyage to the bottom of the sea and long summers on Lake Michigan that led me into diving.
