In 1-H Mr Kelley writes, “So a complete definition can only be the sum of the comments about it.”
There is specific use of “Swivel” in the following:
*4-D-0. RELEASE MOTIONS
…“Swivel”---that is, actually rotate the Left Wrist--through Release into the Vertical Position for Impact.”
*10-11-0-3. PRESSURE POINT #3
When the Wrists “Swivel” back to the Vertical Position during Standard Wrist Action
*10-18-A . STANDARD
…the Hands “Swivel” into Hinge Action Position
Help in locating other book references would be appreciated.
