If I remember correctly, mine did not come with instructions as such,
There was a diagram showing what parts went where.
Be prepared to do some fine file work for the hammer to move freely.
Also, there is a T shaped part that I would call a "Hammer Spring guide rod"
it passes through a hole in the back of the brass "Receiver" and there is a corresponding
hole in the grip that the rod is supposed to pass into. That hole is not deep enough or accurately drilled into the wood. it took me longer to figure that out than anything.
Be care with the pin that holds the Hammer in place also. It was VERY tight on mine.
don't force it or you will crack the hammer.
Also, the spring that goes behind the trigger was not strong enough. I clipped one from a ball point pen to the proper length. and it worked great
