Number of blades does not effect pitch. Since it is a bronze prop it could have "Cup" in the trailing edges of the prop which would effectively act like pitch. Not sure that happened on old props, but it does on new style props. I am sure racers figured out long ago that cup helped the prop hold onto the water.
