The box shows the “Remington/UMC” in the red circle logo on the top label and both end panels.  Also, the end side labels of this box are stamped “.44 Henry R.F. Flat” & “Black Powder”.  Although, darkened slightly with age, the top label is in excellent condition.  But shows no damage or rubbing. The bullet pictured on the lid is marked “44 Henry Flat” & “Model 1866“. The side labels are all intact, only cut for opening, and note: “Specially Adapted for Model 1866 Rifles & Carbines“.

The guarantee label on the bottom of the box is in good condition and printed in both English and Spanish. The box is solid, just showing a natural age induced split seam on the top right side. There are several side seams, both top & bottom, with glued repairs that are very well done and mostly unseen.

History of the .44 Henry rimfire cartridge

One of the great reasons for the success of the Henry Rifle was the development of the self-contained metallic .44 Henry cartridge. In 1854, the Smith & Wesson Company patented a lever action pistol using a toggle action and an integral front-loading magazine. Unfortunately, the “rocket ball” ammunition used with this design left much to be desired. Despite the limitations of the rocket ball ammunition, the rocket ball was used in a number of attempts at making a commercially successful firearm. As a result, this led to the reorganization and creation of the Volcanic Repeating Arms Company.

During this Smith & Wesson reorganization, Oliver Winchester became a major stockholder. Smith & Wesson both dropped out of the Volcanic Arms Co. circa 1855-56 and Oliver Winchester reorganized, again, as the New Haven Arms Co. in 1857. Subsequently, Winchester hired B. Tyler Henry to improve the Volcanic design. Henry went one step further by improving the cartridge. He invented a copper cased self-contained cartridge which made the bullets more reliable. Accordingly, the .44 caliber Henry rimfire cartridge was born. With his new cartridge and S&W’s lever action design, he developed a new rifle. Thus, the Henry Rifle, using the .44 Henry rimfire cartridge, was the first reliable lever action rifle.

Otherwise known as the 1866 “yellowboy”, the improved Henry rifle was also chambered for the .44 Henry Rimfire cartridge.
