The Lindner carbine was an early US cavalry carbine used during the Civil War. Unlike the many metallic cartridge firing carbines that would follow, it was a breechloader that used .58 caliber paper cartridges. An initial order for 892 of them was delivered to the Army, and Lindner went on to make some improvements to the design. By the time his improved version was ready, the paper cartridge had been rendered obsolete by metallic cartridges, and the Army was no longer interested in the guns. To avoid having to purchase them, they refused to send an inspector to Lindner's factory, thus ensuring that none of the guns would pass inspection. A slimy but legal way out of their contract, as the ensuing legal battle was decided in favor of the government and Lindner had to sell his extra guns in Europe.
