This page from "The Sad Sack Squad" in #9 provides four or five clues to Jack Miller. In some other SSWS stories he uses a sound effect he doesn't need that much in mystery or superhero scripts: Peeow for the sound of a shell. As usual, there are other stories in this run that I'm only half-convinced could be Miller's or Herron's; maybe on another pass I'll be better sure of some and add to the list.
Kanigher takes over editing with issue 13. The one story whose writer is not on his records, "Gen. Hunger" in #19, evidently is inventory from Boltinoff. The art is by Howard Sherman, who had a couple of stories in the earliest issues of SSWS but none that I can think of otherwise in the Kanigher books.
