This is a rare full 50-count box of American Metallic Cartridge Company .44-100 shot cartridges for the Winchester Model 1873 lever action rifle or Colt's Frontier Six Shooter Single Action Army revolver. The American Metallic Cartridge Company was active between c. 1891-1898 in South Coventry, Connecticut, as the successor to the Phoenix Metallic Cartridge Company. The shot cartridges contained inside are of the same dimensions as the .44-40 WCF cartridge. The box is of plain cardboard construction with a top label with the American Metallic Cartridge Company logo of an eagle, and black lettering for 50 solid head cartridges of "44-100 CAL." with "SWAGED BULLETS" for the WINCHESTER REPEATING RIFLE-MODEL 1873". One of the ends of the lid also mentions "Colts Frontier Pistol". A few sides of the box lid read "SHOT CARTRIDGES,/Patented Sept. 9th, 1879" in reference to Henry W. Mason's U.S. patent 219,491 for shot cartridges. Provenance: The Charles Marx Collection

Box is fine with some minor age and storage related wear, and opened seals. Cartridges are also fine. This rare full 50-count box of .44-100 shot cartridges would make a fine accessory to accompany a Winchester '73 or Colt Frontier Six Shooter!
