From Project Gutenberg

The "two gun" advocates had relied heavily upon the 1970 findings of Pasadena Criminologist William W. Harper; using a Balliscan, a specialized camera used to photograph a cylindrical object rotated in front of it, he decided that the recovered Kennedy bullet had only one cannelure�a groove imprinted by the manufacturer � while the others had two concentric grooves.
