You're talking about the first issue of the second volume? Well, I think it was still Timely, not Atlas. The internet says:
"Leav was drafted in 1943 and did his military service as an illustrator for U.S. Army magazines,[5] while moonlighting for comic books. Upon returning to civilian life, he drew, per one source,[5] several Captain America stories for Timely Comics, the 1940s precursor of Marvel Comics, but this remain uncorroborated by such standard references as the Grand Comics Database and Atlas Tales, the latter of which lists only two 1942-43 Destroyer stories as Leav's Timely output.[6]"
So yeah, could be.
