All Hero Comics #1 March 1943

[dans]

In the Bulletgirl story The Castaways, Chapter 1: Frozen in Time (by Libby, posted here: www.5earths.info/earth-s/bullets1985-02-1/) there is a reference to "The Man in the Iron Mask", otherwise known as "Hitler's Headsman", from All Hero comics #1, March 1943, in which he fought Spy Smasher. All Hero comics was a one-shot, and I can't find it online. Does anyone own a copy, or have a digital copy I can read or even a synopsis?

I'd like to find out if there is anything unusual about the villain or the story that might explain why he was in the South Seas attacking Lance O'Casey after he had his run-in with Spy Smasher, and figure out why there might be a tie-in with Dan Dare and Carol Clews.

I can probably make something up but I'd rather tie a new story to our existing continuity if there are any good hooks in the original story.
