If a gun has family value the price is not a major consideration. You will never sell the gun anyways. The money it takes to make the gun whole again is less than the amount that a new gun would cost. Plus what else can many of us hand down to our family that will have been with the family for four, five or six generations? Be patient and the parts will be found over time. Ebay is a good place to watch for the parts, plus others on this board often can help. I will keep an eye out for any NID 20's that may be parted out or beaters for you to strip parts off of. As they say you never know what you will see untill you look.
