Stock printed by American Bank Note Co., New York. Jersey City, New Jersey. Rare! The Pomeroy bullet was designed by New Zealander John Pomeroy (1873–1950) as an anti-zeppelin weapon. Pomeroy bullets were supposed to explode when encountering the minimal resistance of fabric envelopes containing hydrogen gas holding the zeppelin aloft. The explosion might produce a larger hole in the fabric than the small diameter bullet and the energy of the explosion might ignite the hydrogen in the presence of atmospheric oxygen outside of the envelope.

John Pomeroy was a bright youth with an exceptional aptitude for technical innovation. At the age of twelve, a hardware store paid him £50 for the design of a support to hold clothes lines above the ground without tipping to one side. Other inventions included a painless rabbit trap, a pneumatic horse collar, improved sheep shears, a fastener to keep ladies' hats in position, and pneumatic leg guards for cricket players. His proposal for dealing with zeppelin bombers was adopted in 1916 as the Cartridge S.A. Ball .303 inch Pomeroy Mark I. It was a standard .303 British cartridge loaded with a 155-grain (10.0 g) cupronickel-jacketed lead bullet including a hollow copper tube filled with 15 grains (0.97 g) of 73% dynamite. Pomeroy's wife reportedly filled the first five thousand bullets with dynamite by hand. In theory, the acceleration of firing the bullet caused the dynamite to separate with the stabilizing porous kieselguhr settling toward the rear of the tube leaving a film of shock-sensitive nitroglycerine at the forward end of the tube. Later production designated Cartridge S.A. Ball PSA .303 inch Mark II used 60% dynamite with the forward tip of the copper tube closed and included a lead shot at the rear end of the tube to increase sensitivity. Archibald Low assisted with the testing of the bullets. Read more at

A stock certificate is issued by businesses, usually companies. A stock is part of the permanent finance of a business. Normally, they are never repaid, and the investor can recover his/her money only by selling to another investor. Most stocks, or also called shares, earn dividends, at the business's discretion, depending on how well it has traded. A stockholder or shareholder is a part-owner of the business that issued the stock certificates.
