Brian, I have the small parts that you may need, and if the front sight base is of the high Navy type, you may want to consider adding on of my new repro Navy rear toggle with the 2 position adjustable rear sights, made in Germany: cast @$200 or Milled like the originals @$400 + S&H. Lugerdoc
hellerarms@webtv.net PS: I can also install these items and tune your luger for an additional fee.
