Schaufelrad-Set Graupner 581 Paddle wheel set.
Contains all parts required for building a pair of paddle
wheels for installation into side-wheel paddlers. All floats
(blades) of the wheels are movably mounted. Their attitude
is eccentrically steered via a system of pushrods this
encures that the floats will remain in a near vertical position
all the time from the moment they enter the water and while
they are submerged. All parts are made of hi-impact plastic
and can be easily assembled.
