Shot shells were traditionally made with a brass head, and a body made of paper (cardboard) In new shells, the carboard is replaced by plastic. Very early shotshells, and special use shotshells were ALL brass. These were expensive and rather scarce- the brasshead/ paper body was much more common.
The value depend on the condition of the shotgun. Have is appraised by a gunsmith or advanced collector. The inlet brass wolves are not original but should not significantly degrade the value if they look well done.
I just purchased the same shot gun with a bird head handle.
I can tell you that your shotgun was made by J. Stevens Arms sometime between 1914 and 1940, the barrel was cut off and the Wells Fargo markings were added by someone trying to make an inexpensive shotgun appear to be a rare collectable firearm. WF guns were not marked with the brass plates and so many "stagecoach guns" have been faked that there is no collector market for any that do not have solid provinence, ie., a bill of sale from the company identifying the make, model, and serial number.
manufacturing turned toward internal hammers about 1870 just about the same time the transition from twist to fluid steel barrels appeared. keep in mind that side hammers still appeared on center fire shotguns using brass cased shotgun shells that first appeared about 1860. if it is a percussion cap shotgun its probably pre 1860.
I would advis you to have a competent gunsmith look your shotgun over first to see if it will fire safely.He can also advise you as to the length of chamber you have.I would only shoot the low brass shells in this shotgun.
Any spent plastic shotgun shells (hulls) should be reusable, as long as the brass is re-sized before reloading. Paper isn't recommended, and brass casings are practically non-reloadable.
Not likely
No, it would go in the "String Family", not the "Brass Family".
There are brass,tungsten,tungsten alloys(w,Ni,Fe,w,Ni,Cu)used to make a barrel
High brass is used to provide more support for a larger charge (of gunpowder, or larger payload), and low brass is for lower energy shotshells.
You have a Marlin model 1896 slide action shotgun, however, it is a Blackpowder shotgun and you will need brass hulls.
What condition is it in, That determines the value. BTW they all had Brass Barrels.
