Like most bylines in this publication, "Maurice Berry" seems to be a house name (and has no other known credits). The artwork is definitely reminiscent of Klaus Nordling.
The "Happy Daze" logo here is the same as in Spitfire Comics (Elliot, 1944 series) #132, and the character ("The Flying Marine") also has a pet parrot named Gabby, so presumably this is supposed to be the same person. That story was drawn by a different (and inferior) artist, however.
