Ranger, I don't know of any instructions. There is only thing ya really need to know about is the hammer spring. Remove the grips. Cock the hammer. If you look at the lower end of the rod the spring is around there will be a hole exposed. Put a pin in that hole. It needs to be something fairly strong. a finnishing nail, or one your wife has lying around somewhere for hanging picture frames. Lower the hammer till the spring tention will hold the spring. With that one item done, dissassembly is pretty much self explainatory.
