Antiaircraft gun carriage. This master machinist lays out the precision parts that go to make up a thirty-seven millimeter anti-aircraft gun carriage. Swift flying planes present a difficult target, the anti-aircraft gun must be a precision instrument. War program production scene in one of Pennsylvania's heavy industry plants now converted to the production of vitally needed military equipment. AETNA. Ellwood CIty, Pennsylvania

Antiaircraft gun carriage. Final inspection of a thirty-seven-millimeter antiaircraft gun carriage assembly. America's war program requires increased production of these precision instruments of protection, designed to bring down the best-armoured, the fastest-flying enemy aircraft. Production scene in a Pennsylvania heavy industrial engineering plant now converted almost entirely to military production. AETNA. Ellwood City, Pennsylvania

Antiaircraft gun carriage. The elevating mechanism is assembled on a thirty-seven-millimeter antiaircraft gun carriage nearing completion. Care and precision is the watchword in the assembling of these mechanisms. A 300-mile-per-hour target requires a precision instrument to allow the gunner to stay with it.

Antiaircraft gun carriage. A worker tests the smooth working precision of the elevating mechanism assembly of a thirty-seven-millimeter anti-aircraft gun carriage. Planes of 300 miles an hour and better present a fast-moving target which requires precision operation in the anti-aircraft gun that must follow their flight to protect America's lives and property. War program production scene in a Pennsylvania heavy industry plant. AETNA. Ellwood City, Pennsylvania

Antiaircraft gun carriage. A casting is machined for the traversing assembly of a thirty-seven millimeter antiaircraft gun carriage. The traversing assembly must be precision-made so that the gunner may follow his swiftly moving target with accuracy. War program production scene in a Pennsylvania heavy industry plant now converted to the production of vitally needed military equipment. AETNA. Ellwood CIty, Pennsylvania

Antiaircraft gun carriage. Axle brackets for a thirty-seven millimeter anti-aircraft gun carriage are machined on this milling machine. Today's fast-moving planes present a target requiring the very best in antiaircraft guns. Carriage and mount are as important as the gun itself for rapid fire power and maneuverability.

Antiaircraft gun carriage. The traversing bearing is installed on a thirty-seven millimeter antiaircraft gun carriage as it moves down the assembly line. These precision-built ball bearing installations are vitally important, for on their unfailing smooth action depends the gunners' ability to follow his rapidly moving target.

Oil burners to machine gun parts. Fixture which holds bare of raw materials from which small pieces, cut to size, are obtained for production of precision parts for Uncle Sam's machine gun squads. Site of these operations is an Eastern factory which has been converted from manufacture of oil burners to production of war essentials. Reif-Rexoil Company, Buffalo, New York

Oswego, New York. Willard DiSantis, sixteen-year old high school boy who made seventy-six model planes for the U.S. Navy, and was awarded the honarary rank of admiral

Three-inch A.A. cartridge cases. Cartridge cases for three-inch antiaircraft shells are produced by a series of operations that transform a flat brass disc into a case ready for loading with propelling charge and shell. Between each operation there is careful washing to remove all scale and adhesion and to leave surfaces clean for later processing. The big Midwest plant doing the work is well equipped to handle it in stride

Production. P-51 "Mustang" fighter planes. The accuracy of a milling machine operation is checked by an inspector in a machine shop at the Inglewood, California, plant of the North American Aviation. The casting being milled will be part of the landing gear of a P-51 fighter plane. This plant produces the battle-tested B-25 "Billy Mitchell" bomber, used in General Doolittle's raid on Tokyo, and the P-51 fighter plane which was first brought into prominence by the British raid on Dieppe

Citations of individual production merit awarded. The first five Citations of Individual Production Merit have been awarded to five war workers, War Production Drive Headquarters has announced. The citation is the highest honor conferred for individual achievement. It is granted only for ideas or suggestions that have an outstanding effect on the entire war effort. Joseph H. Kautsky, Indianapolis, Indiana, an employee of the Lin-Belt Co., was awarded his citation for four suggestions, each technical. He suggested a grinding wheel adapter, which permits higher speeds in internal grindings; a simplification cutting down the number of special internal grinding spindle wheel adapters from twelve to three; the adoption of a precision screw adjustment to the vertical column of dial indicator guages, to get faster adjustments without danger to the dials; and a new method of testing the concentricity of internally ground parts. The picture shows Mr. Kautsky (center) being congratulated by formean Bill Whitaker (right) as Superintendant R. E. Whitney (left) looks on

Production. Pratt and Whitney airplane engines. Cylinder heads for R-1340 Wasp planes are inspected in a large Eastern plant now producing a huge number of fine American engines for our fighting air forces. Pratt and Whitney Aircraft
