US Army cavalrymen out on the Plains in the Indian Wars faced many dangers during their arduous campaigns. Those intrepid horsemen manned isolated forts along the trails out West, protected settlers, miners, and railroad crews from "hostiles", and brought renegade bands back onto the reservation. They were issued the classic M-1873 "Trapdoor" Springfield Carbine, and early on, before the advent of the widespread adoption of the Prairie belt or the introduction of the McKeever pouch, ammo for the Trapdoor Carbine was carried in the specially designed M-1874 Dyer ammo pouch. This US Army Indian Wars Cavalry Trapdoor Springfield Carbine M-1874 Dyer Leather Ammo Pouch is in Good Condition, with moderate overall drying, surface cracking, fragility, and age wear evident. Most interestingly, it bears the classic “US” oval embossed marking at front, sports a fully functional brass stud and brass escutcheon closure flap, and is stamped at the upper back with its maker, the famous “ROCK ISLAND / ARSENAL”. It features fully intact sewn and riveted belt loops at the reverse, exhibits a sheep’s wool lining to keep loose rounds from rattling, and is a fine example of a very rare, original US Army Indian Wars Cavalry Trapdoor Springfield Carbine M-1874 Dyer Leather Ammo Pouch. Lastly, this ammo pouch comes directly from the personal collection of renowned US military firearms author and historian Bruce Canfield, and a signed letter of authenticity stating as such will accompany this piece.
