The Lindner carbine design was a clever solution to the gas leak that plagued many early breech loading firearms. This is one of the reported 892 First Type carbines manufactured based on Edward Lindner's patent for the U.S. Government during the Civil War. They were likely manufactured at Amoskeag Manufacturing Co. Of the 892 First Type carbines manufactured, 391 were delivered to the Michigan Cavalry around November 1861, and 501 were delivered to the 8th West Virginia Mounted Infantry in late 1863. This example has the correct First Type breechblock patent marking: "EDWARD LINDNER'S/PATENT/MARCH 29, 1859," and the lock plate is correctly not marked. A saddle ring is mounted on the left side of the stock. It has a blade front sight and a two leaf rear sight. An inspector's cartouche is stamped near the buttplate tang, and "SE" is carved in the left side of the butt in two different depths. It appears the "E" was only outlined and not finished.
