Two of them were shown in Avition Week 12/1953 in a summary by Kelly Johnson
about the layout of a Mach 2 fighter, that eventually led to the F-104.

Here is a translation of the paragraph:

Some of the new wing types that are being studied to achieve higher velocities. Upper left: ?swept wings? (I am not familiar with the phrase alas en fletcha so this is a guess on my part but it seems to fit) for transonic flight; upper right: Lockheed fighter with straight wing; the three in the center are delta wings; below: bomber and delta wing with ailerons.

"alas en flecha" (please note spelling) is the same as the French "ailes en flèche" (literally "arrow-shaped wings") and indeed means swept wings.
