To take it apart for general cleaning after it has been fired, try this.
Ӣ Remove the ramrod from the pipes.
Ӣ Set the hammer at half-cock.
Ӣ Loosen the screw that holds the lock in place about 2-3 turns. The screw goes thru the stock from the side opposite the lock to the lock.
Ӣ Tap the barrel wedge in the forestock out using something that is thinner than the wedge.
Although a screw driver can be used, it's hardened end may mar the wedge. If your OK with that, use it. Other wise find a piece of aluminum or wood to drive the wedge out of the slot.
Ӣ With the wedge removed, the barrel should lift out of the stock by raising the muzzle end. The rear of the barrel has a hook on it that engages a hole in the tang block.
For most tasks, this will be as far as you need to go with taking the gun apart.
To reassemble the gun, do everything in the reverse but when inserting the rear of the barrel into the tang block, make sure it is in as far as it will go before you try to lower the barrel back into the stock.
If it starts to bind when you try lowering the barrel into place, check the engagement of the breech of the barrel and the tang block.
It needs to be shoved in tight.
Going a bit further, if you want to remove the lock, gently tap the lock screw head with something like a screw driver handle. Then, back the screw out a few more turns and repeat tapping the screw head.
This will drive the lock out of its mortise in the stock.
When it seems to be loose, remove the screw and the lock.
To remove the trigger the trigger guard needs to be removed. Then, loosen the screw in the tang block. This screw screws into the trigger assembly. Once it is removed, the tang block and the trigger can be removed.
