"Belly-buster" hand-crank audio drill. Used during the late 1950s/early 1960s to drill holes into masonry for implanting audio devices. After assembly, the base of the drill was held firmly against the stomach while the handle was cranked manually. This kit came with several drill bits and accessories.
