"Vanishing Oil Tank Cars" is the Human Torch story in All Select Comics 3, Spring/1944.
Compare the upper right-hand caption in the Torch section with the one in the same upper right-hand corner on this page of The Hidden Kingdom" in Charlton's Jungle Jim 24, June/1969 (art by Pat Boyette).
My instinct is to attribute the Torch story to the writer credited on the Jungle Jim one: Joe Gill. Gill is known to have worked at Marvel in the Forties and Fifties, before going to Charlton. The one thing that gives me pause is not knowing when he returned from the service. The Who's Who has him starting at Marvel around 1945, which I don't take as hard and fast, but a story published with a Spring '44 cover date would have to be written in late 1943. Does anybody know when Joe Gill got home from the Pacific?
