Savage 19 23 NRA MICROMETER REAR SIGHT pits on point

Even though it does not look it, this sight retains about 80% original finish on top. There is pitting on the top front point of the sight which could be removed by buffing the area and rebluing. The adjustments work great and the sight needs some cleaning. The bottom of the sight has lost about 50% of it's finish turned brown. The screw came with the sight off an NRA, no rear screw. No other damage or problems.
