This is the 4th or 5th story in this lost comic book series...
...from Captain Wizard #1 (and only) in 1946.
The first two stories were presented (along with some background on the artist) by Staq Mavlen at Atomic Surgery HERE and HERE.
This particular comic publisher, Enwil/Rural Home/Orbit/Universal/Croydon, was a bit...disorganized.
Stories were tossed into comics (which were mostly one-shots) to fill page count without much thought as to how anyone would follow the plotlines.
Astonishingly, most of the strips had continuing storylines!
Another of their characters, Hugh Mann the Impossible Man appeared in three different comics, with the third story printed before the second.
Judging from the fact that the plotline has obviously progressed from the end of his second appearance when we begin this tale, it's safe to speculate that this is the 4th or 5th story in the series.
Are there any more?
Perhaps Staq can get the Time Bubble working and track them down... ;-)
