LIGHT BEAM AIDES POLICE OFFICERS - DETROIT, MICH. - G. Howlett Davis of Detroit (Right) demonstrating a device he has invented which when attached to the barrel of a revolver projects a beam of light that illuminates a small area into which bullets fired from the revolver will hit. This device is expected to be of great use to policemen hunting fugitives or armed criminals in dark places, for once the beam of light picks up the target it can be held and the bullets placed in it. Emerson Osborn is acting as target. This light beam is effective up to 50 feet. 8-20-40
