    For Crust: Combine flour, sugar, cinnamon and salt in medium bowl. Cut in
   butter using pastry blender or 2 knives until mixture resembles coarse
   meal.  Add water and toss mixture gently with fork until evenly moistened,
   Gather gently into ball.  Transfer to lightly floured board and roll into
   circle slightly larger than a deep 10- inch pie plate. Ease pastry into pan
   and flute high edge.  Set aside.
   
    For filling: Preheat oven to 450 F.  Combine all ingredients in large bowl
   and mix well.  Spoon into crust. Bake 10 minutes. Reduce oven temperature
   to 350 F and continue baking until filling is slightly puffed and golden
   brown, about 40 minutes.  (If edges of crust begin to brown too quickly,
   cover with strips of aluminum foil.)
   
    For topping: Meanwhile, combine walnuts, flour, sugars, cinnamon and salt
   in medium bowl and mix well.
    Blend in butter until mixture is crumbly. Spoon over pie and bake 15
   minutes longer.
