Wow, not even a clue for me. That's OK I found it, my original problem was not putting my search in quotes and I got lost in the hits.
For anyone searching in the future, coming upon this post, The Larry Jennings Chop Cup Routine can be found in Vol. 29 p 373 ( That correlates to March 1965),
Back to Mr. Bryant, if you are talking about The Uncanny Chop Cup in the book The Uncanny Scot, you are exactly right, that is a wonderful routine. Skimming the Jennings' version I can already see similarities, I can't wait to really compare the two. They both look great. That book, The Uncanny Scot, is one of the best magic books I've gotten in the last 25 years, I just love it!
Thanks for the input.
