TO TAKE THE GUN APART.
The piece is first dismounted and placed with its casing resting on blocks. Mounting and dismounting are best accomplished by means of a gin. In case of necessity, it may be mounted and dismounted as a field-piece, care being taken to place blocks of wood to receive the gun-frame and to prevent injury to the front sight, or to the barrels.
The operations of taking apart are executed in the following order:
1. Block up the frame and barrels.
2. Remove the hopper.
