Fifty .44 flat rimfire cartridges in a Winchester box with green top label and orange labels on the sides. Top of the box is labeled "50 "WINCHESTER" 50/Trade Mark/.44 FLAT RIMFIRE CARTRIDGES" at the top and "FOR THE/WINCHESTER RIFLE MODEL 1866." towards the bottom with additional text relating to the patent, trade, guarantee and address information.

Very good. The box has some storage/shelf wear and some separation on the lid. Otherwise an intact, rare box of vintage ammunition that is great for display with your Model 1866, Henry, or other compatible rifle.
