This Gun

Fires Triangular Cartridges!
Is a 20-Shot Revolver!
Can Be Loaded While Firing!
Comes With Two Barrel Sizes!
Can Be Converted To a Rifle!

THE revolutionary new Dardick open chamber revolver is as versatile as a six-armed monkey. It comes with two different sized barrels, converts from a pistol to a rifle, fires 20 triangular cartridges, ejects fired cases and can be loaded while firing. The double-action, semiautomatic gun uses the special .38 or .22 Dardick cartridge or, with a simple adapter, any standard ammunition. Open chamber ejection makes it possible to build lighter and faster firing weapons that are more reliable at less cost than standard guns.

Head Measurements Help To Identify Criminals

A device long used by hat stores, to measure the size and shape of a customer’s head, now helps police of Norwalk, Conn., to identify criminals. According to sponsors of the new method,who use it in conjunction with fingerprinting, no two men have heads of exactly the same shape. Therefore, the perforated contour patterns produced by the device will afford a check on a suspect’s identity, and may prove particularly valuable if he has attempted to alter his fingerprints by chemical or surgical means. Since he cannot change the contour of his skull, this would remain as a telltale clew to his identity.

Police Identification System “Fingerprints” Faces

FACES are classified like fingerprints, to index hundreds of thousands of portraits, in the criminal files of Los Angeles County, Calif. A ruled glass screen called a “physiogmograph,” applied to each photograph, enables experts to determine accurately such information as facial height and width, and the size and shape of nose and mouth. Characteristics also noted include position of the ears, height, weight, general build, and the color of hair, eyes, and complexion. Finally, all these items are ingeniously combined in a number-and-letter code symbol, such as 11/5 NUFCFLCHD, under which the picture is filed.

Flashlight Weapon Invented
A COMBINATION flashlight gun has been invented by V. Merifield, of the Los Angeles, Calif., police department. At the pressing of a trigger the device ejects a spray of ammonia or gas from a jet to disable any suspect who might attempt to draw a weapon when the flashlight is aimed.

Have You a Wrong Way Brain?

By PAUL A. CLARKSON

CAN new discoveries about the brain reclaim a million criminals? Can psychological research cut America’s crime bill in half? Can scientists, using drugs and surgery, eliminate dishonest impulses from the minds of crooks?

Questions like these may sound fantastic. Yet developments of recent weeks bring them to the fore. One of the most famous psychiatrists in the world, Dr. Carleton Simon, of New York City, has just announced a revolutionary new theory which may help science control criminal tendencies.

It seems to me that if the two scientists from “Firm A” are geeking out about their work and not paying attention to the “Sweet Young Thing” then they deserve to lose any secrets they may have.

Watch out for that girl, laddie; you might be talking over her head but into her microphone.

AS Willie Shakespeare once said, - “There’s more to this than meets the eye!” This, in the present case, happens to be the bodice of a Sweet Young Thing, said bodice containing microphone, batteries, antenna and transmitter—constituting a miniature radio station with a range of 200-300 feet.

G-Men of the Fields
GUARD NATIONS MELON SUPPLY

By ARTHUR A. STUART

FROM a dark side street, the two inspectors watched the caravan of ancient touring cars and sedans pull out of the big garage. They tailed the procession to the edge of the city. When it was plain that the gang was headed for the coast, the officers speeded ahead to the Jacumba, Calif., checking station, where they waited. Twenty minutes later, the first of the cars came in sight and the flash lights of the officers signaled it over to the side of the road.

New Inventions that Baffle Crooks

by Lew Holt

Inventors working in the cause of law and order, inspired by a recent outbreak of outrageous kidnapings and other crimes, have perfected numerous devices which give the police a new advantage in the perpetual war on criminals. Crime weapons are fully discussed here.

COULD the immortal shade of Sherlock Holmes return to earth, he would find a new delight in using the latest weapons of science to wage war on criminals—criminals, incidentally, of such perverted genius and “big business” organization as to make the notorious Professor Moriarty of Holmes and Watson fame a decided back number.

Tear Gas Gun for the Wrist
A TEAR gas gun effective enough to rout a gang of payroll bandits and small enough to be concealed in a coat sleeve has been invented by Elmer Carlstrom of Chicago, a retired policeman. The gun is worn strapped to the wrist, as shown in the photo below. A piece of catgut, flesh colored and invisible at a glance, is stretched between a ring on the wearer’s finger and the trigger of the gun. The hand can be moved freely in any normal position, but bending the wrist sharply will discharge the weapon. Leather under the muzzle protects the wearer’s arm from being burned by discharge of the gas.
