Mr. Palmer is correct. John Snyder worked at the Olde Magic Boutique in the St. Louis area. It was actually in north county in the Ferguson/Florissant area. John sold a lot of the Rings 'n Things product. That is where I bought most of what I currently own. The rest was purchased from Gene DeVoe's Magic Den. I really miss Gene! What a class act!
Anyway, Mr. Snyder published a manuscript which I still own called the "Pockety Chop" manual. It is a good booklet, 8-1/2" x 11" stapled and contains lots of good ideas. One idea which I believe John claimed as original was a final load of approx. 25 half dollars. What was nice was the gimmick, which was easily made up. The whole routine was based on the RnT pocket-sized Don Alan Chopcup.
In the manuscript, John quotes Don Alan as being very favorable to the material, especially the final load.
Not having read the Don Alan book, is there a suggestion of animosity between the two?
I know that some in the St. Louis magic community had negative things to say about Mr. Snyder, but I never had any issues with him. When I was developing a manipulation routine, he was helpful in locating a nice Palmo ball for my silk routine and a nice large dye tube for Blendo. He also offered some tips that were helpful.
