The statement of ownership lists Martin Goodman as Editor. It is believed that during this period (from Red Raven #1 until the successful debut of Captain America Comics) that Joe Simon was working as an editor on a freelance basis. Therefore he would not have held the official title. This is consistent with Simon's known work editing/packaging Red Raven #1, Daring Mystery #6 and other issues but also stating that he was not made the editor of the entire Timely line of comics until after Captain America proved successful (as stated in his book The Comic Book Makers).
The on-sale date is from the publication date recorded in the Catalog of Copyright Entries, Part 2, Periodicals, 1941, New Series, Vol. 36, No. 1.
