Springfield, Model 1884, Trapdoor Rifle
Model 1884 rifles were produced in the .45-70 caliber.  The rifles had a blued and case-hardened finish with walnut stock bearing the U.S. Inspector's cartouche.

It was the standard military rifle for the U.S. Infantry from the Indian Wars through the Spanish-American War.  A few were used for guard purposes at ports and defense plants in World War I, and sone were donated to the U.S. Navy during World War II for conversion to line throwing gfuns.

The 1884 was made in several models, including the Cadet model with 2-piece trigger guard and 29 1/2" barrel, as opposed to the 32 5/8"  or 36" barrels.
