I have a used Enfield 1887 Mark IV Model 1 for sale. This beautiful antique is chambered in .575/450 caliber black powder (NOT .58, I just had to select something). The barrel is 32.25" long and is in good shape, the rifling is still quite crisp. This rifle was made under the Queen Victoria Era! If this firearm could tell stories! It's in great shape considering it's well over 100 years old! I did verify that the line on the right side of the receiver (near the model/name) is just a scratch and not a crack! The makers marks are still quite visible as well as the markings on the ramrod.
