Writer credit from Craig Delich, per the Who's Who.
Wright Lincoln was a House name at Fiction House in 1939.
Art credits from Ron Goulart via Will Murray and the GCD Error List (21 March 2006), with the original indexer crediting both pencils and inks to Pierce Rice (who did the strip sometime in 1940, but not this story).
Note from Craig Delich: I don't believe Gormley is the artist here. The Who's Who and other sources lists him as doing "Dynamite Thor", which appeared in Weird Comics #6-8, and featured the hero in costume. Thor, God of Thunder, found in Weird Comics #1-5, was set in Valhalla. I've added a ? to Gormley's art credits.
Grant Farrel was given the powers and image of Thor whenever Thor threw his mighty hammer striking Grant.
