Okay, I think it's time for one of the non-SCDers to please explain the difference
between (a) a Buzz Swing (b) a walked swing and (c) a Tulloch turn (other than
handing). Without my Flett & Flett handy, I can't quote the date the Reel of
Tulloch came into being, but late 18thC/ early 19thC sticks in my mind. Whether
the pivot turn was a unique movement at the time is out of my realm.
