[Directions for Cleaning
Set the cock at half-cock, drive out the key that holds the barrel and cylinder to the lock frame, then draw off the barrel and cylinder, by bringing down the lever and forcing the rammer on the partition between the chambers. Take out the nipples. Wash the cylinder and barrel in warm water, dry and oil them thoroughly; oil freely the base pin on which the cylinder revolves.
