An article about Springheel Jack by John Vyner was published in the Flying Saucer Review for May & June in 1961. A few months later it was re-printed in FATE magazine in October.
Blaise and Merlyn Vyner, John's sons, have four drawings by John's friend Colin Forward which seem to be connected with the article in one way or another, they might have been commissioned in the hope of publishing a book.
As yet I haven't actually seen the article so I don't know if the drawings were printed.
Dr David Clarke discussed the article in some depth ( see the link below ). Although he dismisses its content, he acknowledges that it seems to have influenced subsequent thinking on the subject of Springheel Jack ... in my mind, amplifying the kernel of a cultural meme ...

Scales case
On 28 February 1838,[13] nine days after the attack on Miss Alsop, 18-year-old Lucy Scales and her sister were returning home after visiting their brother, a butcher who lived in a respectable part of Limehouse. Miss Scales stated in her deposition to the police that as she and her sister were passing along Green Dragon Alley, they observed a person standing in an angle of the passage. She was walking in front of her sister at the time, and just as she came up to the person, who was wearing a large cloak, he spurted "a quantity of blue flame" in her face, which deprived her of her sight, and so alarmed her, that she instantly dropped to the ground, and was seized with violent fits which continued for several hours.[14]
Her brother added that on the evening in question, he had heard the loud screams of one of his sisters moments after they had left his house and on running up Green Dragon Alley he found his sister Lucy on the ground in a fit, with her sister attempting to hold and support her. She was taken home, and he then learned from his other sister what had happened. She described Lucy's assailant as being of tall, thin, and gentlemanly appearance, covered in a large cloak, and carrying a small lamp or bull's eye lantern similar to those used by the police. The individual did not speak nor did he try to lay hands on them, but instead walked quickly away. Every effort was made by the police to discover the author of these and similar outrages, and several persons were questioned, but were set free.[14]
