No seashell routines, but:
Fans of Dr. Sawa should definitely order from The Chief Genii, the January 1977 (vol. 41 no. 1) back issue, with "Japan's Sawa" on the cover. It will instantly transport you back to the '70s, and the Doctor's clever material still kicks ass.
The cover article has Bill Larsen recounting in his inimitable style his visit with Dr. Sawa on a trip to Japan with Irene and the Shimadas.
The issue features 3 very good tricks:
--the famous "Slot Machine" (about which, in "The Genii Speaks" WWL(Jr) says, "If you can master Sawa's 'Slot Machine' you will have an effect more valuable than several years of subscription"--true to this day, no?)
--a broken and restored spoon effect called "Gary Ueller" (which if memory serves, inspired material from "at least" Messers Weber and Sankey) and
--"Sawa's Lady Bug Trick", a paddle routine using a little branch (you can make) with six leaves and ladybugs that appear and disappear as the branch blows in the breeze...
Yep, that guy's been good for a while now.
