Brian:
The only book with detailed info on the Caille "Sphinx", will be Coin Slot Guide #3, By the late Dick Bueschel,
as shown below. This is from a series of 34 Guides, which he published several years ago. There was originally
100 Guides scheduled, but other book projects held up the continuation of the rest. Occasionally these Guides
show up on eBay, but I think your best chance is to contact Roger Hilden, at Crow River Trading, as he has a
large selection of most coin-op books. Go to his website at (
http://www.crowriver.com).
