The U.S. Navy operated Haiku (Hawaii) Alexandersson alternator TX during WWII, operating from 1942 until 1946.
But it's doubtful that these signals would be received on a domestic set intended for broadcast use.

Yes, strictly speaking, Long Wave is LF not VLF.
I noticed that in "Wireless For The Warrior", in the compendium on enemy radio equipment that quite a lot of German army WW2 sets used LF.
