This is the earliest known rifle to be produced by the Mauser brothers. In collaboration with their partner, American inventor Samuel Norris, they converted the French Model 1867 Chassepot needle-fire rifle into a bolt-action arm capable of utilizing base-primed metallic cartridges. These experimental rifles were also significant due to their self-cocking and primary extraction features which later became standard on all Mauser rifles. This particular example served as the model for U.S. Patent No. 78,603, which was granted to the trio on June 2, 1868. The First Mauser Rifle can be seen at the NRA National Firearms Museum in Fairfax, Virginia.
