DH4 Four Bladed Propeller - Rolls Royce Engine

Comments: Manufactured for a British built DH4 this 4 bladed version was fairly common on British DH4's, while the U.S. built version typically used a 2 blade version. The brass cap nuts shown in the photo are decorative and are part of the mounting bracket used to mount the propeller for display. The 4 bladed version presumably improved ground clearance by shortening the length of each blade, but was never proven to be more effecient or practical than the 2 blade. The DH4 served both as a bomber and a reconnaissance plane during WW1. (As a display propeller this one actually requires less horizontal wall space, since each blade is positioned diagonally.)
