This copy of Ripley's Believe It or Not True Ghost Stories comic was among the coverless comics I picked up a while back. It features four stories of Comics Code approved horror (translation, not horror). But as it turns out, the comic does have justification in calling these "true ghost stories" as at least a couple are in fact based on true legends.
"The Weeping Ghost" tells the story of the murder of King Charles II's illegitimate son by his mistress Nell Gwyn.
While in the comic, Nell throws her baby to its death, the generally accepted legend is she simply hung him out a window until King Charles dubbed the child the Earl of Burford.
These text stories were typically thrown into comics so that they met guidelines for magazine postal rates. I could find no evidence of a Moses Gort.
The Phantom Hands of Dartmoor is based on an urban legend in the English count of Devon.
Tragedy sounds like "Krruummpp!"
I found no information on an urban legend involving a Woodchopper. Woodchippers, yes.
Similarly, I could find no connection of "The Doomsday Express" to any urban legends.
