$50-$150, depending on condition. BTW, those are patent dates, the gun was made at a later time.
The simplest would be a single shot muzzle loading firearm. In modern cartridge firearms, a break action firearm. They are made as rifles, shotguns and pistols.
In short, no. I have a single shot lever action Ithaca rifle, and a turn action Garcia Bronco .22. There have been auto ejecting single shots, and a LOT of bolt action single shots. The "trapdoor" Springfield rifle was not a break action.
Single shot break action? yes.
The CBC MODEL SB 410 BORE SHOTGUN is made in brazil and imported by firearms import and export Corp. located in Miami, Florida it is a break-action single shot shotgun
NEWPORT was a tradename used by the catalog/hardware giant Hibbard, Spencer& Bartlett Co (HS&B) in Chicago up until WW2. The single barrel guns were made by various contract manufacturers such as Iver Johnson and WH Davenport.
it's worth about 75 dollors
Hundreds. They are generally separated into revolvers and pistols (anything not a revolver) But then it becomes complex. There are different types of revolvers, such as single action, double action, top break, tip up, swing out cylinder, etc. There are single shot pistols that are top break, and bolt action. There are double and single action pistols, and even fully automatic (machine pistols). There are shotgun pistols, small caliber pistols, ones that will fit in a vest pocket, and some that have scopes and a bipod. There are antique black powder pistols and revolvers, and pistols with frames made of plastic type polymers. The study of firearms is a VERY broad subject.
