In this Alarming Tales list, note the scripters switched around (from what you might expect from the artwork) on the first two stories in #3.
There were two single-page text stories in each issue (#1's were Black Cat stories); I've entered here only the ones whose author I could tell; Jack Oleck's captions style (Almost, ___...; In the end, ___....) is so distinctive that it's carried through into prose, which is not at all always the case.
There seem to be a number of inkers on the different Kirby stories, or even on diferent pages. Some of the GCD's art attributions on other stories to people like Bob Brown (or, on "12,000 to 1," Jack Kirby) I can say are wrong, but I can't supply a better guess. Reed Crandall had nothing to do with "The Strange Power of Gary Ford," and here I can give the artist's name: Norman Nodel.
I would agree with the GCD indexers that the covers of #1-4 are mostly the work of editor Joe Simon, even if some Kirby material got used in them. When the title returned after a hiatus, like Simon's other Harvey titles at the time, John Severin did the covers to #5 and 6. And Simon did the intro pages to #1-4 (Bob Powell drew #5's and Bernard Baily #6's).
UPDATE: Robin Snyder sent along the Carl Wessler scripting credits, from Wessler's account books (kept like William Woolfolk's). I still see Bob Powell's writing style, as in The Man in Black and Henry Brewster, on "The Monster from 1977 A.D."; I suppose he massaged Wessler's script. The same thing happened with Wessler, Jack Oleck, and Otto Binder at EC for awhile, as Al Feldstein rewrote their scripts into his style at first.
