Only approximately 3,400 of these cadet rifles were manufactured in 1870 and 1871. They are rarer than many of the other trapdoor variations, and many originals have been destroyed or altered over the years. The main difference between the Model 1869 cadets and earlier models is the shorter barrel and the use of new stocks rather than repurposed musket stock. Like the other trapdoors, Erskine S. Allin was the designer and inspector. This example is dated "1870" on the breechblock which is also marked "eagle head/crossed arrows/U.S." The lock plate is marked with the standard Springfield markings including "1863" at the tail. The left side of the barrel and receiver have the matching serial number which falls within the correct special serial number range for the cadets. The barrel is fitted with "U" marked barrel bands and has a fixed front sight and folding ladder rear sight graduated to "9". It is mounted with a nearly full length walnut stock with a "U.S." marked buttplate and the correct two-piece trigger guard. The left stock flat has a single "ESA" inspection cartouche.
