The Winchester 45-75  Centennial cartridge was introduced in 1876 for the Winchester "Centennial"
Lever-Action Rifle.
The Cartridge and rifle were used by Theodore Roosevelt and the Canadian Mounted Police
It was discontinued by Winchester in 1935.
I consider this one of the nicest looking cartridge ever produced.
