I have an 1866 Springfield in 50-70, which may have been used at the Wagon Box Fight in 1867, in which U.S. soldiers had been using 1863 muzzleloaders & the Indians would provoke a volley then charge before the muskets could be reloaded.
Came the day when the soldiers were issued with breechloaders. The chief ordered a feint charge, the initial volley was fired, only now the command was given to fire at will and a steady fire ensued, dropping braves at an appalling rate.
Took several more charges before Big Chief realized the soldiers had more bullets than he had braves. Nice piece of history to own.
I also have a Colt New Model Police 36 caliber percussion cap revolver. It has all matching serial numbers and looks like it was made in the late 1860’s from the serial number.
