The writers already at DC assigned to the feature at this point include Jack Miller and Dave Wood; possibly Dick Wood too, who had worked on it into 1955 at Quality. I'm still working out the authorship of the individual non-Bernstein stories.
It would seem that the only completed story art done at Quality that DC received in the deal is "The Mutiny of the Red Sailors" in 108; the letterer is whoever worked on the title as of 107. "The Threat from the Abyss" may have been passed along to DC as a script; it too is an anti-Communist story of the sort that DC didn't much do on their own (and it's the final story in which the Blackhawk song appears at the end). My opinion is that Bernstein wrote most of the stories here directly for DC; he's moved to Aquaman, Green Arrow, and Congo Bill by the end of 1957.
