An unusual stock certificate issued by The Electric Gun Corporation. It was issued on May 22, 1917 to Enninger & Company. for 100 shares at $1 per share.

The Electric Gun Corporation was organized to manufacture and sell electric guns under patent rights for several electromagnetic-mechanisms by the inventor, Frederick B. MacLaren.

World War I stimulated a strong interest in the improvement of guns in general and, in particular, the first serious investigations of an electrically driven gun. The Electric Gun Corporation intended to begin with the manufacture of a 3-inch field piece to expel a 20-pound projectile at a velocity of 2500 feet per second. The gun was to be smokeless, flash-less, noiseless, and derive power from the nearest electric wire. Several examples were built and demonstrated but interest waned for weapons after the completion of World War I.

MacLaren’s U.S. patent of 1916 described a traveling magnetic wave induction launcher powered by a high-frequency,three-phase generator. In this, the traveling magnetic wave induced currents in the projectile and provided the EM force that accelerated the projectile through the barrel. MacLaren's concepts were reviewed over the years and considered the modern invention of the rail gun (although the concept of electromagnetic artillery went back to the 1880's). In 1937, Princeton engineering professor Edward Northrup reviewed MacLaren's and other's work on the concept to develop what was known as a rail gun.

Early efforts to demonstrate the electromagnetic acceleration of projectiles were limited by the availability of suitable sources of electric power. As electric power became more commonly available and its application understood, experiments with electric guns became more common also. Later engineers improved until today's rail gun slated for US Navy ships.
