This case made for a large frame revolver like the Colt's 1860 Army or Navy or a revolver with a similar frame size. The outside measures 8 1/2" x 20 1/2" and stands 10 " tall and the inside is 6" x 18" x 8 1/2". It has glass on 3 sides and the top with a mirror on the inside back so the revolver can be viewed from all sides. The glass portion of the case lifts off the base for easy access. The back is also finished in walnut so it displays very nicely on a mantle or in the center of a table. This case can be made any size for any type of handgun, long gun, sword, or anything else.
