To Dismount the Revolver.—Half-cock the revolver, loosen the centre-pin catch-screw, draw out the centre-pin, open the gate, and the cylinder can then be withdrawn. To remove the ejector, turn out the ejector-tube screw, then push the front end away from the barrel, and pull it towards the muzzle. The stock can be removed by turning out the two back-strap screws just behind the hammer, and that at the bottom of the strap. Remove the mainspring and guard: the parts of the lock can then be readily separated. The centre-pin bushing should be pushed out for cleaning. To remove the gate, turn out the gate-screw in the lower side of the frame (hidden by the guard); then the gate-spring and catch can be withdrawn and the gate pushed out.
To Assemble the Revolver.—See the directions for dismounting, which should be followed in inverse order. The mainspring is most conveniently mounted by turning in the screw part way, and then swinging around the front end of the mainspring until it bears against the under side of the friction-roll. The cylinder-bushing should be frequently removed for cleaning.
