Thanks to Ian for his clarification... It is likely that The Endless Chain belongs in the list...
Several titles were produced by Supreme in that same format but were not technically titles in this series.
I have found more information (thanks to Doug Atkinson: http://magicref.tripod.com/magref/magchain.htm
) that refers to The Endless Chain pamphlet thus:
Ayling, Will (with Lewis Ganson, Fred Lowe, and Rex Taylor): The Endless Chain. Moves, ideas, patter presentations and routines. Photographed by Will Ayling; in the Supreme 'Know-How' series, Bideford, The Supreme Company, 1983, 44 pg.
Yet it also refers to another pamphlet with Ganson's name associated with it in this way:
Brooke, Ken: The Endless Chain. Instructions by Lewis Ganson. Copyright by Harry Stanley "Unique Magic Studio" London W.1.4 pg. A4
It's quite possible that these are essentially the same titles (or that the 1983 title is an expanded version of the Stanley booklet). In either case, Ganson is not referred at the primary author. The time makes it likely and the description would put it in the series, but would love to confirm with an owner...
Anyone got a copy of any of the latter three titles and can confirm their inclusion?
