The script can be found in T A Whitworth's "Learning the Essential Sequence Dances" (available from Amazon), but the summary is:
Step, point, hesitate (twice). Clockwise square. Step, point, hesitate (twice). Reverse clockwise square (4 x 1/4 turns to L). 3 fwd steps, check, 3 backward steps. Side hover, whisk, step, close.
PS. Whitworth categorises the dance as Modern, not Old Time, and attributes the script to Raymond Addicot, 1978.
