Sky Bird was one of the original plans that used a plastic fin unit from fireworks. Sint they could be slid on and off the tube, that's where the removable fins comment comes from.
See the 1960 catalog here: http://www.ninfinger.org/rockets/ca...s60/60est4.html

Fins are listed as the plastic fin unit to build the Sky Bird.
In the list of plans in the Rocketry handbook is the Sky Bird.
